Another Asteroid Close Call 453

james was one of a number of people that submitted the news that the earth has had another near miss, this time with an asteroid. This particular one is thought to be about 300 meters in length, meaning that if it had struck the earth, it would have destroyed an area of say...South Africa. Not to mention the fall out. But we don't need a better system for watching the stars. Nope. Obviously not.

    • ...watch for the bloody asteroids/comets.

      If you're looking for moderately large dark bodies in space, you do it by watching the stars. Dark bodies like asteroids and comets are, surprisingly enough, dark (and generally opaque). Stars, on the other hand, are bright and have a tendency to not flicker out.

      What all this means is that the way you find dark bodies in space is by comparing lots of pictures of starfields and looking for stars that go out and come back. Since it's unlikely that the star flickered, if it seems to do so then there's a good chance something passed between you and it.

    I am sorry to say it but, I beleive that a direct hit it what is needed to force our governments to take action. Hopefully it will be not too big and in an unpopulated area, but statistically we are bound to get wacked at somepoint.

      Hmm... that old chestnut. Missile defense was supposed to take care of asteroids AND missiles, as mentioned in this [fas.org] and this [ceip.org] article. Somewhere along the line, the populist (and governmental - often one and the same, but that's another article) opinion was that the system would point in more than out. That's where the problem lies.

      Now big tents on the other hand...

      • Yes, the Dome was a bad idea. Yes, most of the public thought so to. No, the government couldn't have cared less and went and spent the money anyway. On the other hand, it made for a good scene in the last Bond movie... ;)
      • I've never seen any missile defense plans that have anything to do with stopping an asteroid. Asteroids are much faster, coming from farther out and much bigger than rogue ICBMs. Every missile defense plan I've seen lacks both the range and firepower to make the least bit of difference to an object this size or bigger.

          Hmmm... You make a good case for pursuing a missile defense system. Since we do have to learn to walk before we can learn to run, solving the easier problem of a missile defense system does looks like an essential step towards a goal of building an asteroid defense system.

        It depends, a hit in the Pacific ocean would cause some nice flooding and tidal waves. A hit in say China or India could wipe out many hundreds of millions of people compared to say say a few thousdand if it hit say Mongolia.
        My favoutie target would be the moon man that would look awesome for a big explosion facing us
        • The moon would be pretty bad actually, as it would at a minumum screw up our tides royally which could have a huge effect on lifes, and certainly the economy. Worse is that a hit on the moon could push the moon into a decaying orbit, and the moon is significanly bigger and WOULD be a global killer :)
          • as it would at a minumum screw up our tides royally
            I think it would take more than the impact of a 300 meter rock to alter the orbit of the 3,500,000 meter moon. But it would probably make one hell of a flash, kick up a dust cloud, and maybe even make an observable change on the face of the moon (if it hit the side that faces us.) That would be one hell of a motivator to start taking the impact threat seriously...
    • isaac asimov wrote a neat book called a choice of catastrophes. it basically talks about the different ways humanity could be destroyed. he addresses being hit by an asteroid or other objects from space. while it is statistically possible it is highly unlikely. he concluded that we will most likely destroy ourselves with disease, famine, and war. this would be caused by overpopulation.

        isaac asimov wrote a neat book called a choice of catastrophes he addresses being hit by an asteroid while it is statistically possible it is highly unlikely.

        Remember, Asimov was writing (in 1980) before Gene Shoemaker's work from the 60s and after became fully accepted. It really wasn't until all the work identifying impact craters on the earth that was inspired at least in part by Shoemaker's work, and by the Alvarez hypothesis on the K-T extinction (i.e., the asteroid that killed the dinosaurs), got underway that astronomers and geologists took the idea of large impacts seriously (most scientists thought that Meteor Crater was an extinct caldera before Shoemaker, despite the name). Also, Sagan et al.'s work on sandstorms in the Martian atmosphere in the 1970s, which helped to provide a possible mechanism for global effects from local impacts, wouldn't have been completely digested by the time Asimov was writing. Though Asimov was right that overpopulation is the most serious of the issues he deals with in the book (and of course few countries outside Asia take the problem seriously), it would be foolish to dismiss the threat of an impact.

      • If we develop the technology to push asteroids around, then there is some chance that it would be used avoid the highly unlikely case of a natural impact in the foreseeable future.

        However, I think that it's more likely that it would be used as a doomsday weapon by some lunatic group or country by pushing an asteroid towards the earth. Given mankind's track record at handling powerful new technologies over the last few thousand years, I'd rather go with the natural odds.

      But then they'll say "Oh, gee, something like that only happens once every 5,000 years, so we have lots of time before the next one now that it's finally happened."

      I'd script it this way:
      Bruce Willis: "On average? What does that mean?"
      Jeff Goldblum: "It means we're about due for three of these."
      Bruce Willis: "Oh."

    • really though: astronomers, physicists, engineers, etc. have all stated many times that there is really no practical asteroid defence system available to us anyways. The article referenced even stated that the astronomers acknowledged that had the asteroid been on a direct impact course with earth, there is nothing we could have done, even with much greater notice.

      I imagine that the best strategy we would be able to implement would be total evacuation of the expected area of destruction. And if we're talking about entire nations being wiped out, i doubt that you could evacuate more than 10% of the population(no doubt the ten richest percent), even with a decades notice. Really, all that an expensive asteroid observation system would give us is advance notice of the date of our death... and really, who wants that?

      After all, look how much good the dinosaurs asteroid observation system did THEM.

    • by Sobrique ( 543255 ) on Monday January 07, 2002 @09:43AM (#2797825) Homepage
      Easy. E=mv^2 IIRC. So take the mass of something that size, multiply by the square of the impact velocity, and that's the 'energy' released by the impact.
      It's not _quite_ the same as a nuclear explosion, but if you get the energy level high enough, then the effects are similar enough that it doesnt matter.
      A kiloton is define as 10^12 calories which is about 4 x 10 ^ 12 joules.
      A 1000 tons of rock would have to hit the earth at about 1 kilometer per second to have a similar effect - which is quite a small speed if you are talking about relative speeds in space... (escape velocity is 7km/sec IIRC)
      Don't know what the mass of that rock would have been, but a 300 metre sphere of rock is going to be _fairly_ heavy. Take some averages, and count a few fingers, and you start realising that several megatonnes of energy are comparatively easy to come by if you're hit by a big chunk of rock travelling at significant speeds.
      (This is, assuming I can count of course.)
      • by at_18 ( 224304 ) on Monday January 07, 2002 @10:47AM (#2798075) Journal
        Actually, the formula is E = (1/2)*mv^2

        Now you have: a 300 m sphere rock at about 3 grams/cm3, which is about 42.000.000 tons. Speeds are in the 10-70 km/sec range, let's take 30km/s, or 30.000 m/s

        The total energy is (1/2)* 4,2*10^12 (grams) * 30.000^2 (m/s)

        or 1,2* 10^22 joules (!)

        if a kiloton is 4*10^12 joules, we have that this asteroid impact has an energy of about 3*10^9 kilotons, or 3 MILLION MEGATONS, all of them released on a single point.

        I hope that my calculations are not too way off...
        • Well, I didn't check your math; but inpact mass and velocity would be reduced by the atmosphere, at least somewhat.

          Also, depending on the composition, the asteroid might disintegrate into smaller fragments -- this would also reduce the impact energy to some extent as the atmosphere would then break down each fragment better than it would the whole.

          Regardless, it would make Fat Man and Little Boy look like roman candles by comparison, I think...

          • but inpact mass and velocity would be reduced by the atmosphere, at least somewhat

            Actually, for impacts of this size, the atmosphere has only a very minor effect. The asteroid would speed through the most dense part (the last 50 km) in a second or two. I would be surprised if this makes more than a 5-10% difference.

              Yeah, sort of like putting a couple of layers of saran wrap on the ground to cushion your fall from a 6-story building.
      • One thing you have to take into consideration is that nuclear detonations aren't terribly efficent at causing damage. Most of the energy is wasted because the energy concentration is too high. To use an analogy, if someone was standing on a building above a crowd, and tips out a jug of water they might get one person wet. A barrel of water might have 20 times the water of the jug, but it's not going to get 20 people wet, it might get 3 or 4 people wet, because the people are too spread out in comparision to the water.
    • How do you calculate the damage?

      You take a 1d10 roll per metric ton of impactor, and the resultant number is the number of square meters, in thousands, of surface land that is flattened/destroyed. If the impactor is above 1000 metric tons, you need a additional rolls to determine volume of matter thrown into the atmosphere, length of time before the matter settles back out, how far the matter spreads, and how much the Earth's albedo might change - but it starts getting complicated...

    ..is tell us when we're all going to die.

    We only get about a months notice of such close passes anyway and there is no way we're going to be able to get a 'Bruce Willis and mates' crew up into orbit in 30 days. A proper asteroid defence system is likely to be at least a decade away, as it is likely to require a number of hefty nukes to persuade an oncoming 300m+ asteroid that it doesn't have right of way.

    Besides, I'd feel distinctly nervous about having a space based system loaded with a several very big nukes right above our heads; just imagine what could happen if a very small object hit the system and destroyed it, knocking the bits back into earths gravity......whilst I know you wouldn't get a nuclear explosion, what chances fallout in a similar manner to a "dirty" sub-nuclear weapon ?
    • We can actually get several decades notice. But we have to find them first, of course.

      From Nasa's FAQs About NEO Impacts [nasa.gov]:

      How much warning will we have?
      With at least half of even the larger NEOs remaining undiscovered, the most likely warning today would be zero -- the first indication of a collision would be the flash of light and the shaking of the ground as it hit. In contrast, if the current surveys actually discover a NEO on a collision course, we would expect many decades of warning. Any NEO that is going to hit the Earth will swing near our planet many times before it hits, and it should be discovered by comprehensive sky searches. This is the purpose of the Spaceguard Survey. In almost all cases, we will either have a long lead time or none at all.

      Anyway, if we had a decent sky survey system, we wouldn't have them just haning around, they'd be off deflecting the rocks we know will hit the Earth in a few hundred years.
  • That's right. I'm not a big fan of dumping large amounts of dollars into lookin' around for asteroids.

    Why? It's simple. I don't want to divert money allocated to other basic research projects... projects that can significantly help this effort. If we increase funding for basic science research, we'll have two longer term positives:

    1. Basic science money can have immediate benefits today.

    - There are lots of critical problems on earth now, above and beyond asteroid impacts. Many of these problems need research dollars now.

    - Asking for a billion now to watch for something that may or may not happen any time soon isn't going to please a lot of people, especially where there are more immediate issues on the table.

    2. The money dedicated to basic research can effectively accomplish the goal of watching for and (hopefully) averting a long-term disaster.

    - Money spent on science research today can help build more effective, lower cost, and more technically able solutions to the problem.

    Spend a dumb billion today, or a smarter million tomorrow. That's the choice.

    Now wait a minute. I remember about the time "Deep Impact" came out in the theaters, scientists assured us that the chances of a large asteroid hitting the earth were extremely remote. And now large asteroids are barely missing us? Have these assumptions been called into question?

      You need to define "large" and "barely missing", to even understand what those assumptions are saying.

      First, we're doing pretty well at tracking the really large earth-grazing asteroids now - for rocks at least a kilometer in diameter (picture the "little guy" that hit at the end of Deep Impact) we're tracking an estimated ~90% instead of 10% of them now, and the big improvement has come in the last five years or so.

      For the stuff smaller than a kilometer (which don't threaten civilization, but can still be large enough to make much of New York City a memory), I don't know that we're doing much tracking at all. So what's your definition of "large"? Thanks to the heavy ocean cover and relatively sparse city covering of the land, odds are we'll get hit in a nice relatively non-fatal location before a city-buster earns its name. And we'll get hundreds or thousands of near misses before then. What's your definition of "barely missing"? I've heard it to refer to anything passing inside the moon's orbit, which is a target with 3,600 times the cross section of Earth. That's a near miss on a cosmic scale, not on a human one.

      It's hard to set odds on something like this, but the most informed I've seen would give us about even odds of having a populated area smashed up (damage as much as a trillion dollars) sometime in the next millenium. Not such bad odds that we want to start putting up an "asteroid defense shield", but bad enough that some other valuable activities (pointing more telescopes at the sky, cataloguing asteroids, improving launch vehicle technology) become more valuable for this secondary reason.
      • Thanks to the heavy ocean cover and relatively sparse city covering of the land, odds are we'll get hit in a nice relatively non-fatal location before a city-buster earns its name.

        Well, from what I can imagine, we would be much more lucky if the asteroid hit a big city, than if it hit the ocean. Imagine the waves! Now consider the fact that most people live somewhat close to the sea...

        I think a large unpopulated land-based area such as Antarctica might be the best. An additional benefit might be that most of the stuff that would be thrown into the atmoshpere would be ice instead of dirt, thus not totally blocking the sun.

        But of course, I'm just speculating, I have neither the time, interest or knowledge to do real calculations.

    The reason earth asteroid collision defense is not a huge priority is, as far as I can tell, there aren't any viable solutions. There are many positive monitoring [nasa.gov] projects [dmtelescope.org] in development stages, but no real solutions. [freeserve.co.uk] According to that last project, we would have had to have intercepted our little 300 meter friend a full earth's orbit away with a 1 megaton warhead detonated on the surface to alter its course enough to not squish us. Considering how long before interception a missile would have to be launched, and the requisite amount of fuel, this is not practicle for, say, defense against a 1 km asteroid.

    Nasa knows [nasa.gov] about 47 1km asteroids in near-earth orbits, any of which could make bickering about the RIAA rather short-lived. Their website claims that the best reason to study NEO's, as we don't have an active defense, is to "allow us to store food and supplies and to evacuate regions near ground zero." This is not the sort of confidence that inspires politicians to open their wallet, nor should it.

    But we don't need a better system for watching the stars. Nope. Obviously not.

    Being an astronomer I probably shouldn't say this, because a pile of cash would rain down on me if somebody decided we needed to monitor the skies 24/7, but what the heck:

    The risk isn't that high. Really.

    We should rather spend our time ending wars. You may say, we can never end wars. Actually, all the nobel peace prize winners I've talked to think we can, so! ;-)

    But on the other hand, I'd really like to monitor the skies 24/7, but such a system should not be designed with one application in mind, it should be designed with the goal of enabling all kinds of projects. For example, I'd like to see a global, dense network of Liquid Mirror Telescopes. That could be used to look for NEOs too.

    • IANANPPW (Nobel Peace Prize Winner) but is occurs to me that the chances of eliminating war are somewhat less than the chances of me winning the lottery.

      The issue is one of world view. The folks that bombed the US earnestly believed that they were doing the right thing. Their world view teaches that elimination of those who refuse to adopt their world view is appropriate.

      You could then argue that the problem is one of religion - merely eliminate religion and the problem is resolved.

      However, if one chooses an atheistic world view, it is not illogical to act in one's perceived best interest to the detriment of others.

      I'm not accusing atheists of selfishly abusing others, I'm just suggesting that behavior of that sort is not entirely inconsistent with the lack of objective measurements of right and wrong.

      And finally, the existance of playground bullies tells us that there will be those who choose force to accomplish their goals regardless of whether it can be morally justified.

      Sometimes force is the only way to stop people bent on forcing their world view on others. Neville Chamberlain believed that peace could be accomplished through appeasement. He was wrong.

        Exactly. Your example illustrates differences in world view. There are many people in the world would put Dubya above those two in a top ten list of dangerous morons who will gladly use violence to further their aims. For the average person on the planet, the chance of being harmed by a stupid decision from Bush is far greater than the threat posed by CNN's villain de jour.

        The New War Against Terror

        Noam Chomsky October 18, 2001 - Transcribed from audio recorded at
        The Technology & Culture Forum at MIT

        Everyone knows it's the TV people who run the world [crowd laugher].

        I just got orders that I'm supposed to be here, not there. Well
        the last talk I gave at this forum was on a light pleasant topic.

        It was about how humans are an endangered species and given the
        nature of their institutions they are likely to destroy themselves
        in a fairly short time. So this time there is a little relief and
        we have a pleasant topic instead, the new war on terror. Unfortunately,
        the world keeps coming up with things that make it more and more
        horrible as we proceed.

        Assume 2 Conditions for this Talk

        I'm going to assume 2 conditions for this talk.

        The first one is just what I assume to be recognition of fact. That
        is that the events of September 11 were a horrendous atrocity
        probably the most devastating instant human toll of any crime in
        history, outside of war.

        The second assumption has to do with the goals. I'm assuming that
        our goal is that we are interested in reducing the likelihood of
        such crimes whether they are against us or against someone else.

        If you don't accept those two assumptions, then what I say will
        not be addressed to you. If we do accept them, then a number of
        questions arise, closely related ones, which merit a good deal of
        thought.

        The 5 Questions

        One question, and by far the most important one is what is happening
        right now? Implicit in that is what can we do about it? The 2nd
        has to do with the very common assumption that what happened on
        September 11 is a historic event, one which will change history.

        I tend to agree with that. I think it's true. It was a historic
        event and the question we should be asking is exactly why? The 3rd
        question has to do with the title, The War Against Terrorism.

        Exactly what is it? And there is a related question, namely what
        is terrorism? The 4th question which is narrower but important has
        to do with the origins of the crimes of September 11th. And the
        5th question that I want to talk a little about is what policy
        options there are in fighting this war against terrorism and dealing
        with the situations that led to it.

        I'll say a few things about each. Glad to go beyond in discussion
        and don't hesitate to bring up other questions. These are ones that
        come to my mind as prominent but you may easily and plausibly have
        other choices.

        1. What's Happening Right Now?

        Starvation of 3 to 4 Million People

        Well let's start with right now. I'll talk about the situation in
        Afghanistan. I'll just keep to uncontroversial sources like the
        New York Times [crowd laughter]. According to the New York Times
        there are 7 to 8 million people in Afghanistan on the verge of
        starvation. That was true actually before September 11th. They were
        surviving on international aid. On September 16th, the Times
        reported, I'm quoting it, that the United States demanded from
        Pakistan the elimination of truck convoys that provide much of the
        food and other supplies to Afghanistan's civilian population. As
        far as I could determine there was no reaction in the United States
        or for that matter in Europe. I was on national radio all over
        Europe the next day.

        There was no reaction in the United States or in Europe to my
        knowledge to the demand to impose massive starvation on millions
        of people. The threat of military strikes right after September..around
        that time forced the removal of international aid workers that
        crippled the assistance programs.

        Actually, I am quoting again from the New York Times. Refugees
        reaching Pakistan after arduous journeys from AF are describing
        scenes of desperation and fear at home as the threat of American
        led military attacks turns their long running misery into a potential
        catastrophe. The country was on a lifeline and we just cut the
        line. Quoting an evacuated aid worker, in the New York Times
        Magazine.

        The World Food Program, the UN program, which is the main one by
        far, were able to resume after 3 weeks in early October, they began
        to resume at a lower level, resume food shipments. They don't have
        international aid workers within, so the distribution system is
        hampered. That was suspended as soon as the bombing began. They
        then resumed but at a lower pace while aid agencies leveled scathing
        condemnations of US airdrops, condemning them as propaganda tools
        which are probably doing more harm than good. That happens to be
        quoting the London Financial Times but it is easy to continue.

        After the first week of bombing, the New York Times reported on a
        back page inside a column on something else, that by the arithmetic
        of the United Nations there will soon be 7.5 million Afghans in
        acute need of even a loaf of bread and there are only a few weeks
        left before the harsh winter will make deliveries to many areas
        totally impossible, continuing to quote, but with bombs falling
        the delivery rate is down to = of what is needed. Casual comment.

        Which tells us that Western civilization is anticipating the
        slaughter of, well do the arithmetic, 3-4 million people or something
        like that. On the same day, the leader of Western civilization
        dismissed with contempt, once again, offers of negotiation for
        delivery of the alleged target, Osama bin Laden, and a request for
        some evidence to substantiate the demand for total capitulation.

        It was dismissed. On the same day the Special Rapporteur of the UN
        in charge of food pleaded with the United States to stop the bombing
        to try to save millions of victims. As far as I'm aware that was
        unreported. That was Monday. Yesterday the major aid agencies OXFAM
        and Christian Aid and others joined in that plea. You can't find
        a report in the New York Times. There was a line in the Boston
        Globe, hidden in a story about another topic, Kashmir.

        Silent Genocide

        Well we could easily go on.but all of that.first of all indicates
        to us what's happening. Looks like what's happening is some sort
        of silent genocide. It also gives a good deal of insight into the
        elite culture, the culture that we are part of. It indicates that
        whatever, what will happen we don't know, but plans are being made
        and programs implemented on the assumption that they may lead to
        the death of several million people in the next couple of weeks.very
        casually with no comment, no particular thought about it, that's
        just kind of normal, here and in a good part of Europe. Not in the
        rest of the world. In fact not even in much of Europe. So if you
        read the Irish press or the press in Scotlandthat close, reactions
        are very different. Well that's what's happening now. What's
        happening now is very much under our control. We can do a lot to
        affect what's happening. And that's roughly it.

        2. Why was it a Historic Event?

        National Territory Attacked

        Alright let's turn to the slightly more abstract question, forgetting
        for the moment that we are in the midst of apparently trying to
        murder 3 or 4 million people, not Taliban of course, their victims.

        Let's go backturn to the question of the historic event that took
        place on September 11th. As I said, I think that's correct. It was
        a historic event. Not unfortunately because of its scale, unpleasant
        to think about, but in terms of the scale it's not that unusual.

        I did say it's the worstprobably the worst instant human toll of
        any crime. And that may be true. But there are terrorist crimes
        with effects a bit more drawn out that are more extreme, unfortunately.

        Nevertheless, it's a historic event because there was a change.

        The change was the direction in which the guns were pointed. That's
        new. Radically new. So, take US history.

        The last time that the national territory of the United States was
        under attack, or for that matter, even threatened was when the
        British burned down Washington in 1814. There have been manyit was
        common to bring up Pearl Harbor but that's not a good analogy. The
        Japanese, what ever you think about it, the Japanese bombed military
        bases in 2 US colonies not the national territory; colonies which
        had been taken from their inhabitants in not a very pretty way.

        This is the national territory that's been attacked on a large
        scale, you can find a few fringe examples but this is unique.

        During these close to 200 years, we, the United States expelled or
        mostly exterminated the indigenous population, that's many millions
        of people, conquered half of Mexico, carried out depredations all
        over the region, Caribbean and Central America, sometimes beyond,
        conquered Hawaii and the Philippines, killing several hundred
        thousand Filipinos in the process.

        Since the Second World War, it has extended its reach around the
        world in ways I don't have to describe. But it was always killing
        someone else, the fighting was somewhere else, it was others who
        were getting slaughtered. Not here. Not the national territory.

        Europe

        In the case of Europe, the change is even more dramatic because
        its history is even more horrendous than ours. We are an offshoot
        of Europe, basically.

        For hundreds of years, Europe has been casually slaughtering people
        all over the world. That's how they conquered the world, not by
        handing out candy to babies. During this period, Europe did suffer
        murderous wars, but that was European killers murdering one another.

        The main sport of Europe for hundreds of years was slaughtering
        one another. The only reason that it came to an end in 1945, was.it
        had nothing to do with Democracy or not making war with each other
        and other fashionable notions. It had to do with the fact that
        everyone understood that the next time they play the game it was
        going to be the end for the world. Because the Europeans, including
        us, had developed such massive weapons of destruction that that
        game just had to be over. And it goes back hundreds of years. In
        the 17th century, about probably 40% of the entire population of
        Germany was wiped out in one war.

        But during this whole bloody murderous period, it was Europeans
        slaughtering each other, and Europeans slaughtering people elsewhere.

        The Congo didn't attack Belgium, India didn't attack England,
        Algeria didn't attack France.

        It's uniform. There are again small exceptions, but pretty small
        in scale, certainly invisible in the scale of what Europe and us
        were doing to the rest of the world. This is the first change. The
        first time that the guns have been pointed the other way. And in
        my opinion that's probably why you see such different reactions on
        the two sides of the Irish Sea which I have noticed, incidentally,
        in many interviews on both sides, national radio on both sides.

        The world looks very different depending on whether you are holding
        the leash or whether you are being whipped by it for hundreds of
        years, very different. So I think the shock and surprise in Europe
        and its offshoots, like here, is very understandable. It is a
        historic event but regrettably not in scale, in something else and
        a reason why the rest of the worldmost of the rest of the world
        looks at it quite differently. Not lacking sympathy for the victims
        of the atrocity or being horrified by them, that's almost uniform,
        but viewing it from a different perspective.

        Something we might want to understand.

        3. What is the War Against Terrorism?

        Well, let's go to the third question, 'What is the war against
        terrorism?' and a side question, 'What's terrorism?'. The war
        against terrorism has been described in high places as a struggle
        against a plague, a cancer which is spread by barbarians, by
        "depraved opponents of civilization itself." That's a feeling that
        I share. The words I'm quoting, however, happen to be from 20 years
        ago. Those arethat's President Reagan and his Secretary of State.

        The Reagan administration came into office 20 years ago declaring
        that the war against international terrorism would be the core of
        our foreign policy.describing it in terms of the kind I just
        mentioned and others. And it was the core of our foreign policy.

        The Reagan administration responded to this plague spread by depraved
        opponents of civilization itself by creating an extraordinary
        international terrorist network, totally unprecedented in scale,
        which carried out massive atrocities all over the world, primarily.well,
        partly nearby, but not only there. I won't run through the record,
        you're all educated people, so I'm sure you learned about it in
        High School. [crowd laughter]

        Reagan-US War Against Nicaragua

        But I'll just mention one case which is totally uncontroversial,
        so we might as well not argue about it, by no means the most extreme
        but uncontroversial. It's uncontroversial because of the judgments
        of the highest international authorities the International Court
        of Justice, the World Court, and the UN Security Council. So this
        one is uncontroversial, at least among people who have some minimal
        concern for international law, human rights, justice and other
        things like that. And now I'll leave you an exercise. You can
        estimate the size of that category by simply asking how often this
        uncontroversial case has been mentioned in the commentary of the
        last month. And it's a particularly relevant one, not only because
        it is uncontroversial, but because it does offer a precedent as to
        how a law abiding state would respond todid respond in fact to
        international terrorism, which is uncontroversial. And was even
        more extreme than the events of September 11th. I'm talking about
        the Reagan-US war against Nicaragua which left tens of thousands
        of people dead, the country ruined, perhaps beyond recovery.

        Nicaragua's Response

        Nicaragua did respond. They didn't respond by setting off bombs in
        Washington. They responded by taking it to the World Court, presenting
        a case, they had no problem putting together evidence. The World
        Court accepted their case, ruled in their favor, condemned what
        they called the "unlawful use of force," which is another word for
        international terrorism, by the United States, ordered the United
        States to terminate the crime and to pay massive reparations. The
        United States, of course, dismissed the court judgment with total
        contempt and announced that it would not accept the jurisdiction
        of the court henceforth. Then Nicaragua went to the UN Security
        Council which considered a resolution calling on all states to
        observe international law. No one was mentioned but everyone
        understood. The United States vetoed the resolution. It now stands
        as the only state on record which has both been condemned by the
        World Court for international terrorism and has vetoed a Security
        Council resolution calling on states to observe international law.

        Nicaragua then went to the General Assembly where there is technically
        no veto but a negative US vote amounts to a veto. It passed a
        similar resolution with only the United States, Israel, and El
        Salvador opposed. The following year again, this time the United
        States could only rally Israel to the cause, so 2 votes opposed to
        observing international law. At that point, Nicaragua couldn't do
        anything lawful. It tried all the measures. They don't work in a
        world that is ruled by force.

        This case is uncontroversial but it's by no means the most extreme.

        We gain a lot of insight into our own culture and society and what's
        happening now by asking 'how much we know about all this? How much
        we talk about it? How much you learn about it in school? How much
        it's all over the front pages?' And this is only the beginning.

        The United States responded to the World Court and the Security
        Council by immediately escalating the war very quickly, that was
        a bipartisan decision incidentally. The terms of the war were also
        changed. For the first time there were official orders givenofficial
        orders to the terrorist army to attack what are called "soft
        targets," meaning undefended civilian targets, and to keep away
        from the Nicaraguan army. They were able to do that because the
        United States had total control of the air over Nicaragua and the
        mercenary army was supplied with advanced communication equipment,
        it wasn't a guerilla army in the normal sense and could get
        instructions about the disposition of the Nicaraguan army forces
        so they could attack agricultural collectives, health clinics, and
        so onsoft targets with impunity. Those were the official orders.

        What was the Reaction Here?

        What was the reaction? It was known. There was a reaction to it.

        The policy was regarded as sensible by left liberal opinion. So
        Michael Kinsley who represents the left in mainstream discussion,
        wrote an article in which he said that we shouldn't be too quick
        to criticize this policy as Human Rights Watch had just done. He
        said a "sensible policy" must "meet the test of cost benefit
        analysis" -- that is, I'm quoting now, that is the analysis of "the
        amount of blood and misery that will be poured in, and the likelihood
        that democracy will emerge at the other end." Democracy as the US
        understands the term, which is graphically illustrated in the
        surrounding countries. Notice that it is axiomatic that the United
        States, US elites, have the right to conduct the analysis and to
        pursue the project if it passes their tests. And it did pass their
        tests. It worked. When Nicaragua finally succumbed to superpower
        assault, commentators openly and cheerfully lauded the success of
        the methods that were adopted and described them accurately. So
        I'll quote Time Magazine just to pick one. They lauded the success
        of the methods adopted: "to wreck the economy and prosecute a long
        and deadly proxy war until the exhausted natives overthrow the
        unwanted government themselves,"

        with a cost to us that is "minimal," and leaving the victims "with
        wrecked bridges, sabotaged power stations, and ruined farms," and
        thus providing the US candidate with a "winning issue": "ending
        the impoverishment of the people of Nicaragua." The New York Times
        had a headline saying "Americans United in Joy" at this outcome.

        Terrorism Works - Terrorism is not the Weapon of the Weak

        That is the culture in which we live and it reveals several facts.

        One is the fact that terrorism works. It doesn't fail. It works.

        Violence usually works. That's world history. Secondly, it's a very
        serious analytic error to say, as is commonly done, that terrorism
        is the weapon of the weak. Like other means of violence, it's
        primarily a weapon of the strong, overwhelmingly, in fact. It is
        held to be a weapon of the weak because the strong also control
        the doctrinal systems and their terror doesn't count as terror.

        Now that's close to universal. I can't think of a historical
        exception, even the worst mass murderers view the world that way.

        So pick the Nazis. They weren't carrying out terror in occupied
        Europe. They were protecting the local population from the terrorisms
        of the partisans. And like other resistance movements, there was
        terrorism. The Nazis were carrying out counter terror. Furthermore,
        the United States essentially agreed with that. After the war, the
        US army did extensive studies of Nazi counter terror operations in
        Europe. First I should say that the US picked them up and began
        carrying them out itself, often against the same targets, the former
        resistance. But the military also studied the Nazi methods published
        interesting studies, sometimes critical of them because they were
        inefficiently carried out, so a critical analysis, you didn't do
        this right, you did that right, but those methods with the advice
        of Wermacht officers who were brought over here became the manuals
        of counter insurgency, of counter terror, of low intensity conflict,
        as it is called, and are the manuals, and are the procedures that
        are being used. So it's not just that the Nazis did it. It's that
        it was regarded as the right thing to do by the leaders of western
        civilization, that is us, who then proceeded to do it themselves.

        Terrorism is not the weapon of the weak. It is the weapon of those
        who are against 'us' whoever 'us' happens to be. And if you can
        find a historical exception to that, I'd be interested in seeing
        it.

        Nature of our Culture - How We Regard Terrorism

        Well, an interesting indication of the nature of our culture, our
        high culture, is the way in which all of this is regarded. One way
        it's regarded is just suppressing it. So almost nobody has ever
        heard of it. And the power of American propaganda and doctrine is
        so strong that even among the victims it's barely known. I mean,
        when you talk about this to people in Argentina, you have to remind
        them. Oh, yeah, that happened, we forgot about it. It's deeply
        suppressed. The sheer consequences of the monopoly of violence can
        be very powerful in ideological and other terms.

        The Idea that Nicaragua Might Have The Right To Defend Itself

        Well, one illuminating aspect of our own attitude toward terrorism
        is the reaction to the idea that Nicaragua might have the right to
        defend itself.

        Actually I went through this in some detail with database searches
        and that sort of thing. The idea that Nicaragua might have the
        right to defend itself was considered outrageous. There is virtually
        nothing in mainstream commentary indicating that Nicaragua might
        have that right. And that fact was exploited by the Reagan
        administration and its propaganda in an interesting way. Those of
        you who were around in that time will remember that they periodically
        floated rumors that the Nicaraguans were getting MIG jets, jets
        from Russia. At that point the hawks and the doves split. The hawks
        said, 'ok, let's bomb 'em.' The doves said, `wait a minute, let's
        see if the rumors are true. And if the rumors are true, then let's
        bomb them.

        Because they are a threat to the United States.' Why, incidentally
        were they getting MIGs? Well they tried to get jet planes from
        European countries but the United States put pressure on its allies
        so that it wouldn't send them means of defense because they wanted
        them to turn to the Russians. That's good for propaganda purposes.

        Then they become a threat to us. Remember, they were just 2 days
        march from Harlingen, Texas. We actually declared a national
        emergency in 1985 to protect the country from the threat of Nicaragua.

        And it stayed in force. So it was much better for them to get arms
        from the Russians. Why would they want jet planes? Well, for the
        reasons I already mentioned. The United States had total control
        over their airspace, and was using that to provide instructions to
        the terrorist army to enable them to attack soft targets without
        running into the army that might defend them. Everyone knew that
        that was the reason.

        They are not going to use their jet planes for anything else. But
        the idea that Nicaragua should be permitted to defend its airspace
        against a superpower attack that is directing terrorist forces to
        attack undefended civilian targets, that was considered in the
        United States as outrageous and uniformly so. Exceptions are so
        slight, you know I can practically list them. I don't suggest that
        you take my word for this. Have a look. That includes our own
        senators, incidentally.

        Honduras - The Appointment of John Negroponte as Ambassador to the
        United Nations

        Another illustration of how we regard terrorism is happening right
        now. The US has just appointed an ambassador to the United Nations
        to lead the war against terrorism a couple weeks ago. Who is he?

        Well, his name is John Negroponte. He was the US ambassador in the
        fiefdom, which is what it is, of Honduras in the early 1980's.

        There was a little fuss made about the fact that he must have been
        aware, as he certainly was, of the large-scale murders and other
        atrocities that were being carried out by the security forces in
        Honduras that we were supporting. But that's a small part of it.

        As proconsul of Honduras, as he was called there, he was the local
        supervisor for the terrorist war based in Honduras, for which his
        government was condemned by the world court and then the Security
        Council in a vetoed resolution. And he was just appointed as the
        UN Ambassador to lead the war against terror. Another small experiment
        you can do is check and see what the reaction was to this. Well,
        I will tell you what you are going to find, but find it for yourself.

        Now that tells us a lot about the war against terrorism and a lot
        about ourselves.

        After the United States took over the country again under the
        conditions that were so graphically described by the press, the
        country was pretty much destroyed in the 1980's, but it has totally
        collapsed since in every respect just about. Economically it has
        declined sharply since the US take over, democratically and in
        every other respect. It's now the second poorest country in the
        Hemisphere. I should say.I'm not going to talk about it, but I
        mentioned that I picked up Nicaragua because it is an uncontroversial
        case. If you look at the other states in the region, the state
        terror was far more extreme and it again traces back to Washington
        and that's by no means all.

          US & UK Backed South African Attacks

          It was happening elsewhere in the world too, take say Africa. During
          the Reagan years alone, South African attacks, backed by the United
          States and Britain, US/UK-backed South African attacks against the
          neighboring countries killed about a million and a half people and
          left 60 billion dollars in damage and countries destroyed. And if
          we go around the world, we can add more examples.

          Now that was the first war against terror of which I've given a
          small sample. Are we supposed to pay attention to that? Or kind of
          think that that might be relevant? After all it's not exactly
          ancient history. Well, evidently not as you can tell by looking at
          the current discussion of the war on terror which has been the
          leading topic for the last month.

          Haiti, Guatemala, and Nicaragua

          I mentioned that Nicaragua has now become the 2nd poorest country
          in the hemisphere. What's the poorest country? Well that's of course
          Haiti which also happens to be the victim of most US intervention
          in the 20th century by a long shot. We left it totally devastated.

          It's the poorest country.

          Nicaragua is second ranked in degree of US intervention in the 20th
          century.

          It is the 2nd poorest. Actually, it is vying with Guatemala. They
          interchange every year or two as to who's the second poorest. And
          they also vie as to who is the leading target of US military
          intervention. We're supposed to think that all of this is some sort
          of accident. That is has nothing to do with anything that happened
          in history. Maybe.

          Colombia and Turkey

          The worst human rights violator in the 1990's is Colombia, by a
          long shot.

          It's also, by far, the leading recipient of US military aid in the
          1990's maintaining the terror and human rights violations. In 1999,
          Colombia replaced Turkey as the leading recipient of US arms
          worldwide, that is excluding Israel and Egypt which are a separate
          category. And that tells us a lot more about the war on terror
          right now, in fact.

          Why was Turkey getting such a huge flow of US arms? Well if you
          take a look at the flow of US arms to Turkey, Turkey always got a
          lot of US arms. It's strategically placed, a member of NATO, and
          so on. But the arms flow to Turkey went up very sharply in 1984.

          It didn't have anything to do with the cold war. I mean Russian
          was collapsing. And it stayed high from 1984 to 1999 when it reduced
          and it was replaced in the lead by Colombia. What happened from
          1984 to 1999? Well, in 1984, [Turkey] launched a major terrorist
          war against Kurds in southeastern Turkey. And that's when US aid
          went up, military aid. And this was not pistols. This was jet
          planes, tanks, military training, and so on. And it stayed high as
          the atrocities escalated through the 1990's. Aid followed it. The
          peak year was 1997. In 1997, US military aid to Turkey was more
          than in the entire period 1950 to 1983, that is the cold war period,
          which is an indication of how much the cold war has affected policy.

          And the results were awesome. This led to 2-3 million refugees.

          Some of the worst ethnic cleansing of the late 1990's. Tens of
          thousands of people killed, 3500 towns and villages destroyed, way
          more than Kosovo, even under NATO bombs. And the United States was
          providing 80% of the arms, increasing as the atrocities increased,
          peaking in 1997. It declined in 1999 because, once again, terror
          worked as it usually does when carried out by its major agents,
          mainly the powerful. So by 1999, Turkish terror, called of course
          counter-terror, but as I said, that's universal, it worked. Therefore
          Turkey was replaced by Colombia which had not yet succeeded in its
          terrorist war. And therefore had to move into first place as
          recipient of US arms.

          Self Congratulation on the Part of Western Intellectuals

          Well, what makes this all particularly striking is that all of this
          was taking place right in the midst of a huge flood of self-congratulation
          on the part of Western intellectuals which probably has no counterpart
          in history. I mean you all remember it. It was just a couple years
          ago. Massive self-adulation about how for the first time in history
          we are so magnificent; that we are standing up for principles and
          values; dedicated to ending inhumanity everywhere in the new era
          of this-and-that, and so-on-and-so-forth. And we certainly can't
          tolerate atrocities right near the borders of NATO. That was repeated
          over and over. Only within the borders of NATO where we can not
          only can tolerate much worse atrocities but contribute to them.

          Another insight into Western civilization and our own, is how often
          was this brought up? Try to look. I won't repeat it. But it's
          instructive. It's a pretty impressive feat for a propaganda system
          to carry this off in a free society. It's pretty amazing. I don't
          think you could do this in a totalitarian state.

          Turkey is Very Grateful

          And Turkey is very grateful. Just a few days ago, Prime Minister
          Ecevit announced that Turkey would join the coalition against
          terror, very enthusiastically, even more so than others. In fact,
          he said they would contribute troops which others have not willing
          to do. And he explained why.

          He said, We owe a debt of gratitude to the United States because
          the United States was the only country that was willing to contribute
          so massively to our own, in his words "counter-terrorist" war, that
          is to our own massive ethnic cleansing and atrocities and terror.

          Other countries helped a little, but they stayed back. The United
          States, on the other hand, contributed enthusiastically and decisively
          and was able to do so because of the silence, servility might be
          the right word, of the educated classes who could easily find out
          about it. It's a free country after all. You can read human rights
          reports. You can read all sorts of stuff. But we chose to contribute
          to the atrocities and Turkey is very happy, they owe us a debt of
          gratitude for that and therefore will contribute troops just as
          during the war in Serbia. Turkey was very much praised for using
          its F-16's which we supplied it to bomb Serbia exactly as it had
          been doing with the same planes against its own population up until
          the time when it finally succeeded in crushing internal terror as
          they called it. And as usual, as always, resistance does include
          terror. Its true of the American Revolution. That's true of every
          case I know. Just as its true that those who have a monopoly of
          violence talk about themselves as carrying out counter terror.

          The Coalition - Including Algeria, Russia, China, Indonesia

          Now that's pretty impressive and that has to do with the coalition
          that is now being organized to fight the war against terror. And
          it's very interesting to see how that coalition is being described.

          So have a look at this morning's Christian Science Monitor. That's
          a good newspaper. One of the best international newspapers, with
          real coverage of the world. The lead story, the front-page story,
          is about how the United States, you know people used to dislike
          the United States but now they are beginning to respect it, and
          they are very happy about the way that the US is leading the war
          against terror. And the prime example, well in fact the only serious
          example, the others are a joke, is Algeria. Turns out that Algeria
          is very enthusiastic about the US war against terror. The person
          who wrote the article is an expert on Africa. He must know that
          Algeria is one of the most vicious terrorist states in the world
          and has been carrying out horrendous terror against its own population
          in the past couple of years, in fact. For a while, this was under
          wraps. But it was finally exposed in France by defectors from the
          Algerian army. It's all over the place there and in England and so
          on. But here, we're very proud because one of the worst terrorist
          states in the world is now enthusiastically welcoming the US war
          on terror and in fact is cheering on the United States to lead the
          war. That shows how popular we are getting.

          And if you look at the coalition that is being formed against terror
          it tells you a lot more. A leading member of the coalition is Russia
          which is delighted to have the United States support its murderous
          terrorist war in Chechnya instead of occasionally criticizing it
          in the background. China is joining enthusiastically. It's delighted
          to have support for the atrocities it's carrying out in western
          China against, what it called, Muslim secessionists. Turkey, as I
          mentioned, is very happy with the war against terror. They are
          experts. Algeria, Indonesia delighted to have even more US support
          for atrocities it is carrying out in Ache and elsewhere. Now we
          can run through the list, the list of the states that have joined
          the coalition against terror is quite impressive. They have a
          characteristic in common.

          They are certainly among the leading terrorist states in the world.

          And they happen to be led by the world champion.

          What is Terrorism?

          Well that brings us back to the question, what is terrorism? I have
          been assuming we understand it. Well, what is it? Well, there happen
          to be some easy answers to this. There is an official definition.

          You can find it in the US code or in US army manuals. A brief
          statement of it taken from a US army manual, is fair enough, is
          that terror is the calculated use of violence or the threat of
          violence to attain political or religious ideological goals through
          intimidation, coercion, or instilling fear. That's terrorism. That's
          a fair enough definition. I think it is reasonable to accept that.

          The problem is that it can't be accepted because if you accept
          that, all the wrong consequences follow. For example, all the
          consequences I have just been reviewing. Now there is a major effort
          right now at the UN to try to develop a comprehensive treaty on
          terrorism. When Kofi Annan got the Nobel prize the other day, you
          will notice he was reported as saying that we should stop wasting
          time on this and really get down to it.

          But there's a problem. If you use the official definition of
          terrorism in the comprehensive treaty you are going to get completely
          the wrong results.

          So that can't be done. In fact, it is even worse than that. If you
          take a look at the definition of Low Intensity Warfare which is
          official US policy you find that it is a very close paraphrase of
          what I just read. In fact, Low Intensity Conflict is just another
          name for terrorism. That's why all countries, as far as I know,
          call whatever horrendous acts they are carrying out, counter
          terrorism. We happen to call it Counter Insurgency or Low Intensity
          Conflict. So that's a serious problem. You can't use the actual
          definitions. You've got to carefully find a definition that doesn't
          have all the wrong consequences.

          Why did the United States and Israel Vote Against a Major Resolution
          Condemning Terrorism?

          There are some other problems. Some of them came up in December
          1987, at the peak of the first war on terrorism, that's when the
          furor over the plague was peaking. The United Nations General
          Assembly passed a very strong resolution against terrorism, condemning
          the plague in the strongest terms, calling on every state to fight
          against it in every possible way. It passed unanimously. One country,
          Honduras abstained. Two votes against; the usual two, United States
          and Israel. Why should the United States and Israel vote against
          a major resolution condemning terrorism in the strongest terms, in
          fact pretty much the terms that the Reagan administration was using?

          Well, there is a reason. There is one paragraph in that long
          resolution which says that nothing in this resolution infringes on
          the rights of people struggling against racist and colonialist
          regimes or foreign military occupation to continue with their
          resistance with the assistance of others, other states, states
          outside in their just cause. Well, the United States and Israel
          can't accept that. The main reason that they couldn't at the time
          was because of South Africa. South Africa was an ally, officially
          called an ally. There was a terrorist force in South Africa. It
          was called the African National Congress. They were a terrorist
          force officially. South Africa in contrast was an ally and we
          certainly couldn't support actions by a terrorist group struggling
          against a racist regime. That would be impossible.

          And of course there is another one. Namely the Israeli occupied
          territories, now going into its 35th year. Supported primarily by
          the United States in blocking a diplomatic settlement for 30 years
          now, still is. And you can't have that. There is another one at
          the time. Israel was occupying Southern Lebanon and was being
          combated by what the US calls a terrorist force, Hizbullah, which
          in fact succeeded in driving Israel out of Lebanon. And we can't
          allow anyone to struggle against a military occupation when it is
          one that we support so therefore the US and Israel had to vote
          against the major UN resolution on terrorism. And I mentioned before
          that a US vote againstis essentially a veto. Which is only half
          the story. It also vetoes it from history. So none of this was ever
          reported and none of it appeared in the annals of terrorism. If
          you look at the scholarly work on terrorism and so on, nothing that
          I just mentioned appears. The reason is that it has got the wrong
          people holding the guns. You have to carefully hone the definitions
          and the scholarship and so on so that you come out with the right
          conclusions; otherwise it is not respectable scholarship and
          honorable journalism. Well, these are some of problems that are
          hampering the effort to develop a comprehensive treaty against
          terrorism. Maybe we should have an academic conference or something
          to try to see if we can figure out a way of defining terrorism so
          that it comes out with just the right answers, not the wrong answers.

          That won't be easy.

          4. What are the Origins of the September 11 Crime?

          Well, let's drop that and turn to the 4th question, What are the
          origins of the September 11 crimes? Here we have to make a distinction
          between 2 categories which shouldn't be run together. One is the
          actual agents of the crime, the other is kind of a reservoir of at
          least sympathy, sometimes support that they appeal to even among
          people who very much oppose the criminals and the actions. And
          those are 2 different things.

          Category 1: The Likely Perpetrators

          Well, with regard to the perpetrators, in a certain sense we are
          not really clear. The United States either is unable or unwilling
          to provide any evidence, any meaningful evidence. There was a sort
          of a play a week or two ago when Tony Blair was set up to try to
          present it. I don't exactly know what the purpose of this was.

          Maybe so that the US could look as though it's holding back on some
          secret evidence that it can't reveal or that Tony Blair could strike
          proper Churchillian poses or something or other. Whatever the PR
          [public relations] reasons were, he gave a presentation which was
          in serious circles considered so absurd that it was barely even
          mentioned. So the Wall Street Journal, for example, one of the more
          serious papers had a small story on page 12, I think, in which they
          pointed out that there was not much evidence and then they quoted
          some high US official as saying that it didn't matter whether there
          was any evidence because they were going to do it anyway. So why
          bother with the evidence? The more ideological press, like the New
          York Times and others, they had big front-page headlines. But the
          Wall Street Journal reaction was reasonable and if you look at the
          so-called evidence you can see why. But let's assume that it's
          true. It is astonishing to me how weak the evidence was. I sort of
          thought you could do better than that without any intelligence
          service [audience laughter]. In fact, remember this was after weeks
          of the most intensive investigation in history of all the intelligence
          services of the western world working overtime trying to put
          something together. And it was a prima facie, it was a very strong
          case even before you had anything. And it ended up about where it
          started, with a prima facie case. So let's assume that it is true.

          So let's assume that, it looked obvious the first day, still does,
          that the actual perpetrators come from the radical Islamic, here
          called, fundamentalist networks of which the bin Laden network is
          undoubtedly a significant part. Whether they were involved or not
          nobody knows. It doesn't really matter much.

          Where did they come from?

          That's the background, those networks. Well, where do they come
          from? We know all about that. Nobody knows about that better than
          the CIA because it helped organize them and it nurtured them for
          a long time. They were brought together in the 1980's actually by
          the CIA and its associates elsewhere:

          Pakistan, Britain, France, Saudi Arabia, Egypt, China was involved,
          they may have been involved a little bit earlier, maybe by 1978.

          The idea was to try to harass the Russians, the common enemy.

          According to President Carter's National Security Advisor, Zbigniew
          Brzezinski, the US got involved in mid 1979. Do you remember, just
          to put the dates right, that Russia invaded Afghanistan in December
          1979. Ok. According to Brzezinski, the US support for the mujahedin
          fighting against the government began 6 months earlier. He is very
          proud of that. He says we drew the Russians into, in his words, an
          Afghan trap, by supporting the mujahedin, getting them to invade,
          getting them into the trap. Now then we could develop this terrific
          mercenary army.

          Not a small one, maybe 100,000 men or so bringing together the best
          killers they could find, who were radical Islamist fanatics from
          around North Africa, Saudi Arabia.anywhere they could find them.

          They were often called the Afghanis but many of them, like bin
          Laden, were not Afghans. They were brought by the CIA and its
          friends from elsewhere. Whether Brzezinski is telling the truth or
          not, I don't know. He may have been bragging, he is apparently very
          proud of it, knowing the consequences incidentally. But maybe it's
          true. We'll know someday if the documents are ever released.

          Anyway, that's his perception. By January 1980 it is not even in
          doubt that the US was organizing the Afghanis and this massive
          military force to try to cause the Russians maximal trouble. It
          was a legitimate thing for the Afghans to fight the Russian invasion.

          But the US intervention was not helping the Afghans. In fact, it
          helped destroy the country and much more.

          The Afghanis, so called, had their own...it did force the Russians
          to withdrew, finally. Although many analysts believe that it probably
          delayed their withdrawal because they were trying to get out of
          it. Anyway, whatever, they did withdraw.

          Meanwhile, the terrorist forces that the CIA was organizing, arming,
          and training were pursuing their own agenda, right away. It was no
          secret. One of the first acts was in 1981 when they assassinated
          the President of Egypt, who was one of the most enthusiastic of
          their creators. In 1983, one suicide bomber, who may or may not
          have been connected, it's pretty shadowy, nobody knows. But one
          suicide bomber drove the US army-military out of Lebanon.

          And it continued. They have their own agenda. The US was happy to
          mobilize them to fight its cause but meanwhile they are doing their
          own thing. They were clear very about it. After 1989, when the
          Russians had withdrawn, they simply turned elsewhere. Since then
          they have been fighting in Chechnya, Western China, Bosnia, Kashmir,
          South East Asia, North Africa, all over the place.

          The Are Telling Us What They Think

          They are telling us just what they think. The United States wants
          to silence the one free television channel in the Arab world because
          it's broadcasting a whole range of things from Powell over to Osama
          bin Laden. So the US is now joining the repressive regimes of the
          Arab world that try to shut it up.

          But if you listen to it, if you listen to what bin Laden says, it's
          worth it. There is plenty of interviews. And there are plenty of
          interviews by leading Western reporters, if you don't want to listen
          to his own voice, Robert Fisk and others. And what he has been
          saying is pretty consistent for a long time. He's not the only one
          but maybe he is the most eloquent. It's not only consistent over
          a long time, it is consistent with their actions.

          So there is every reason to take it seriously. Their prime enemy
          is what they call the corrupt and oppressive authoritarian brutal
          regimes of the Arab world and when the say that they get quite a
          resonance in the region.

          They also want to defend and they want to replace them by properly
          Islamist governments. That's where they lose the people of the
          region. But up till then, they are with them. From their point of
          view, even Saudi Arabia, the most extreme fundamentalist state in
          the world, I suppose, short of the Taliban, which is an offshoot,
          even that's not Islamist enough for them. Ok, at that point, they
          get very little support, but up until that point they get plenty
          of support. Also they want to defend Muslims elsewhere. They hate
          the Russians like poison, but as soon as the Russians pulled out
          of Afghanistan, they stopped carrying out terrorist acts in Russia
          as they had been doing with CIA backing before that within Russia,
          not just in Afghanistan. They did move over to Chechnya. But there
          they are defending Muslims against a Russian invasion. Same with
          all the other places I mentioned. From their point of view, they
          are defending the Muslims against the infidels. And they are very
          clear about it and that is what they have been doing.

          Why did they turn against the United States?

          Now why did they turn against the United States? Well that had to
          do with what they call the US invasion of Saudi Arabia. In 1990,
          the US established permanent military bases in Saudi Arabia which
          from their point of view is comparable to a Russian invasion of
          Afghanistan except that Saudi Arabia is way more important. That's
          the home of the holiest sites of Islam. And that is when their
          activities turned against the Unites States. If you recall, in 1993
          they tried to blow up the World Trade Center. Got part of the way,
          but not the whole way and that was only part of it. The plans were
          to blow up the UN building, the Holland and Lincoln tunnels, the
          FBI building. I think there were others on the list. Well, they
          sort of got part way, but not all the way. One person who is jailed
          for that, finally, among the people who were jailed, was a Egyptian
          cleric who had been brought into the United States over the objections
          of the Immigration Service, thanks to the intervention of the CIA
          which wanted to help out their friend. A couple years later he was
          blowing up the World Trade Center. And this has been going on all
          over. I'm not going to run through the list but it's, if you want
          to understand it, it's consistent. It's a consistent picture. It's
          described in words. It's revealed in practice for 20 years. There
          is no reason not to take it seriously. That's the first category,
          the likely perpetrators.

          Category 2: What about the reservoir of support?

          What about the reservoir of support? Well, it's not hard to find
          out what that is. One of the good things that has happened since
          September 11 is that some of the press and some of the discussion
          has begun to open up to some of these things. The best one to my
          knowledge is the Wall Street Journal which right away began to run,
          within a couple of days, serious reports, searching serious reports,
          on the reasons why the people of the region, even though they hate
          bin Laden and despise everything he is doing, nevertheless support
          him in many ways and even regard him as the conscience of Islam,
          as one said. Now the Wall Street Journal and others, they are not
          surveying public opinion. They are surveying the opinion of their
          friends: bankers, professionals, international lawyers, businessmen
          tied to the United States, people who they interview in McDonalds
          restaurant, which is an elegant restaurant there, wearing fancy
          American clothes. That's the people they are interviewing because
          they want to find out what their attitudes are. And their attitudes
          are very explicit and very clear and in many ways consonant with
          the message of bin Laden and others. They are very angry at the
          United States because of its support of authoritarian and brutal
          regimes; its intervention to block any move towards democracy; its
          intervention to stop economic development; its policies of devastating
          the civilian societies of Iraq while strengthening Saddam Hussein;

          and they remember, even if we prefer not to, that the United States
          and Britain supported Saddam Hussein right through his worst
          atrocities, including the gassing of the Kurds, bin Laden brings
          that up constantly, and they know it even if we don't want to.

          And of course their support for the Israeli military occupation
          which is harsh and brutal. It is now in its 35th year. The US has
          been providing the overwhelming economic, military, and diplomatic
          support for it, and still does. And they know that and they don't
          like it. Especially when that is paired with US policy towards
          Iraq, towards the Iraqi civilian society which is getting destroyed.

          Ok, those are the reasons roughly. And when bin Laden gives those
          reasons, people recognize it and support it.

          Now that's not the way people here like to think about it, at least
          educated liberal opinion. They like the following line which has
          been all over the press, mostly from left liberals, incidentally.

          I have not done a real study but I think right wing opinion has
          generally been more honest. But if you look at say at the New York
          Times at the first op-ed they ran by Ronald Steel, serious left
          liberal intellectual. He asks Why do they hate us? This is the same
          day, I think, that the Wall Street Journal was running the survey
          on why they hate us. So he says "They hate us because we champion
          a new world order of capitalism, individualism, secularism, and
          democracy that should be the norm everywhere." That's why they hate
          us. The same day the Wall Street Journal is surveying the opinions
          of bankers, professionals, international lawyers and saying `look,
          we hate you because you are blocking democracy, you are preventing
          economic development, you are supporting brutal regimes, terrorist
          regimes and you are doing these horrible things in the region.' A
          couple days later, Anthony Lewis, way out on the left, explained
          that the terrorist seek only "apocalyptic nihilism," nothing more
          and nothing we do matters. The only consequence of our actions, he
          says, that could be harmful is that it makes it harder for Arabs
          to join in the coalition's anti-terrorism effort. But beyond that,
          everything we do is irrelevant.

          Well, you know, that's got the advantage of being sort of comforting.

          It makes you feel good about yourself, and how wonderful you are.

          It enables us to evade the consequences of our actions. It has a
          couple of defects. One is it is at total variance with everything
          we know. And another defect is that it is a perfect way to ensure
          that you escalate the cycle of violence. If you want to live with
          your head buried in the sand and pretend they hate us because
          they're opposed to globalization, that's why they killed Sadat 20
          years ago, and fought the Russians, tried to blow up the World
          Trade Center in 1993. And these are all people who are in the midst
          of corporate globalization but if you want to believe that,
          yehcomforting. And it is a great way to make sure that violence
          escalates. That's tribal violence. You did something to me, I'll
          do something worse to you. I don't care what the reasons are. We
          just keep going that way. And that's a way to do it. Pretty much
          straight, left-liberal opinion.

      You also have to consider the fact that nuclear explosions in space behave differently than nuclear explosions in the Earth's atmosphere. A nuclear device is primarily a source of soft x-rays. Since the atmosphere is relatively opaque to soft x-rays, the energy is converted to thermal energy and visible light by absorption and re-emission. This produces the flash, blast wave and thermal pulse. In space, you get a burst of soft x-rays and little else. The nuclear device would have to be very close to the asteroid, so that the soft x-rays were absorbed by the surface of the asteroid and converted into thermal energy.

    Sure, the monitoring system would be pointless in terms of saving ourselves, but where it would be most useful would be in extending the anarchy before the impact. Say from 30days to a full year.


    Now, see that raises an interesting point.

    Anarchy scares the controlling players of any political power structure, so who's to say that those in charge would share sky-watch information with the populace if they had it?

    NASA, back during the Reagan years, had this really low profile military mirror version of itself; A whole second program complete with it's own shuttles which made space runs to plant military satellites in orbit. There's a lot of very expensive & very powerful junk up there which uses classified technologies far in advance of what John Q. Private Sector is allowed to sell in his hard drives. I'd be pretty surprised if there wasn't already enough hardware up there to do decent asteroid surveillance. --In fact, while it might seem like a long shot, I don't think it's that long a shot. . . I'd be willing to gamble that the American government knows a whole lot more about what's going on in Earth's vicinity than they talk about.

    Of course, the way things seem to be run on this planet, I'd also be willing to gamble that even with the right hardware and regular reports, wishful thinking is far more pleasing to the mind, and far more distracting. Probably something along the lines of; "Yech! I don't want to worry about this asteroid stuff. I'm sure I'll be okay. I just need to make a pile of luxury resources for my wife and kids before the planet becomes a toxic waste land. This asteroid stuff only happens to poor people. Or at least, I'm sure it's possible to arrange it so it works out that way. . ."

    There are many groups out there now watching the skys for us. The largest is a government project called LINEAR [mit.edu] based at Lincoln Labs. They find more than half of the new NEO (Near earth orbit) asteroids each year that are found. They have a telescope down in New Mexico and have the largest CCD (2560x1960 res) in the market. From their webpage, you can see they have found at least 727 NEO's. So there are a LOT of asteroids comming near us. But in space, near is still very far away. So unpack those bunkers and return to real life, we're still safe for a while. Also, the rate of finding new NEO's is decreasing, so that means that we've (humans) found most of the asteroids that can endanger us.

    By all means, I agree that spending more money for space-research in general would be a good thing to do, including charting the orbits of anyything close to earth.

    But it's sort of in the nature of these things that "near misses" will be very common compared to actual hits. Let's look at the numbers:

    • The earth has a radius of about 6300 km.
    • This gives a volume of about 10^12 km^3
    • This asteroid was at the closest about 830000 km from earth
    • A sphere with a radius of 830000 has a volume of about 2.5*10^18

    If we divide these numbers, we find that an object will be this close to earth on the average something a bit more than 2 million times as often as it actually hits the earth.

    So, if an asteroid this size hits earth on the average once every 500000 years, then we should expect that one comes this close to earth on the average 4 times a year.

    Offcourse I'm simplifying a lot here, and offcourse this is statistics, we migth just as well be hit one month from now. All I'm saying is that it's not very surprising that something comes "this close" fairly often.

  • Life on our beloved and only planet has survived many impacts of big (let's say caliber >= 1km) and small size. The big bangs sometimes caused a fallout winter for a few human generations, occasionally, if ground zero contained it, including radioactive material, causing more mutations in the fauna and flora for some time. But that was about it. Life went on.

    Today, however, a special kind of landmines endangers the continuity of any, let's say vertebrates, after the next big impact. Our nuclear facilities all over the planet are only safe as long as their cooling systems are working. The statics of these facilities are set to withstand the strongest 'natural' earthquakes.
    Unfortunately an impact of an asteroid of decent size causes much stronger quakes. Depending on its energy, incoming angle, hit area etc. this will cause from just a few to complete worldwide nuclear meltdowns.

    Any solution how to defuse this minefield should get you at least a Nobel prize.

    If a 100 metre asteroid were to crash into earth, and hit a country with nuclear capability, it would appear at first to be a high yield nuclear attack. Minutes/hours later, it would easily be confirmed for what it really is, but during those crucial seconds where the country in question thinks they're under nuclear attack, might panic and respond by launching their own attack, especially if they're currently having hostilities with another country at the time.

    Now, once they launch an attack, what will the rest of the nations of the world do? By the time everyone figures out exactly what happened, half a dozen nations might be actively involved in a nuclear war. Of course, this seems a bit paranoid, but this is the world we live in.

    Its very possible that a 100 meter asteroid could sneak up on us and hit with little or no warning. At least if we have a few days warning, we can evacuate ground zero and all affected nations will know what is REALLY happening and won't panic and create more problems in the process.

    Should we invest trillions of $$$ in defensive measures against this type of threat? Not now. We aren't even sure exactly what the threat would be. A rocky asteroid would present a different threat, and therefore a different solution compared to one comprised primarily of metal. We would require a different approach to deflecting them. And if we only discover them a month before impact, there is nothing we could do anyways, unless its a VERY small asteroid, and even then, the most we could probably do is adjust the location of ground zero, and not miss the earth entirely. Any solution will require the cumulative effects of time to work properly.
