I see a problem with that... to fight the Iowa we would need to call in the Yamato... but to do that, we would need to recover it from the bottom of the ocean... and it was put there by a bunch of vintage aircraft...

Your words make little sense to me. Of course you talk about upgraded AA systems, but thinking that there are "perfect" systems that make something invulnerable is like thinking that I may beat a marathon runner just by deciding to not slow my pace.

I am in doubt, I treat my books like ordinary possessions but also, once in a while I have to shake out the sand and food of the rest of my ordinary possessions, too. What would you chose?

But it is "all or nothing" intimidation, and that has a lot of disvantages.

If you say "obey my order X or I fire" then either:

1: They obey you, you get your short place objetive but appear as the international mad man. Also, as it is easy, you will surely step your demands leading to option 2

2: they don't obey you, you have either to back off or kill thousands of people (at the minimum) to make your point. Even if your opponent has no nuclear deterrence itself, the very fact of appearing to the world as someone capable of launching a nuclear first strike will aim a lot of missiles at you.

So, the MAD is effective to ensure that your enemy does not attempt to destroy you, but for subtler situations it is not so useful. Think how the USA and the URSS still fought a lot of proxy wars even with their nuclear arsenals. In that sense, an aircraft carrier is way more flexible.

Remember that war is a continuation of politics, not the other way around...

I stopped reading when he suggested that current air carriers could be destroyed by "a swarm of iranians flying Cessnas" (I didn't know Iranians had that many Cessnas) or with a German V2 (yes, really). That guy is a joke, and presents any information as if he had a personal issues with aircraft carriers (maybe one of them ran over his mother?)

Don't forget the ceiling falling on the head of that guy that was dumb enough to go to work wearing a red sweater.

Have you read your own link? It says it can track an aircraft at 480 km. Now, assuming that just area is the only concern (and that radar waves are not altered when crossing the ionosphere), an space object with an area of 0.25m^2 (which can easily destroy a rocket/satellite) would be undetectable at just 100km. And that is just the lower limit of "space", and assumes that the radar is vertically under the object.

Ok, you can ride in my car.

I strongly disagree. The OP is right, since someday in the future the kid will be a computer user, he need to learn now computer architecture. Everyone knows that without knowing computer architecture you cannot use a computer!

I did the same to my son when it came to the car; until the time he was able to explain me internal combustion engine and the operation of gas vs diesel motors, I did not allow him to use the car; I would be driving it and he would run by my side.

He still has not convinced me that he knows well enough about central heating, though. Until that, he is sleeping outside. I really hope he learns it before winter settles in.

Ships with life support. And, IIRC, even using just a minuscule power, soon the power source will be unable to provide it.

The good news is that as a phone sanitizer, I get to go first!

Also, we do not even have the experience of building something that can stay 10 years in space without constant support from Earth...

It just makes for some headlines, for a long time.

Those generations were also those of racial lynching, rise of fascism (hello American Legion), Japanese internment, social tension (Bonus Army)...

The difference that you see is the difference between living in a small community were everyone was known and falling to be "a good people" to the community could meant hardships, and living in a city where you can be a dick to everyone all day because you are not likely to found that people again. Also, do not forget that kids are usually shielded from most of the rough things that happen, so they memories usually are sweeter than reality was.

I mean, I grow some plants that require lots of sunlight but that for reasons beyond my power cannot be cultivated in the open air.

If the NASA sends me a couple of these atoms, I can assure them that I will use them on my plants, that I will keep a serious control of its growth and that I will tell them if some unexpected toxic byproduct appears in them.

Who would stop Caesar troops from taking New Vegas, if not for me?

A little offtopic, but your post reminds me of something I read not so long ago

"If religions say that life is eternal, why are they so worried about what you do in your first century?"
