US Revamping Its Nuclear Arsenal 342

FreedomFirstThenPeac writes: As a former Cold Warrior (both launch officer side and staff analytical mathematician side), I now appreciate the bitterness I saw in former WW2 warriors when they would see a Japanese car. According to the NY Times, a new assembly plant in Kansas is "part of a nationwide wave of atomic revitalization that includes plans for a new generation of weapon carriers. This expansion comes under a president who campaigned for 'a nuclear-free world' and made disarmament a main goal of American defense policy." Mind you, Mutual Assured Destruction is a dangerous path, and one we managed to negotiate only because we were lucky (and we were) and because we were careful (and we were).

As a strategy, it only works with rational people (e.g., world powers with lots to lose) who might have irrational expectations that they will win in the long run. (The rapid fall of imperialist Russia was helpful — I have seen blackboard talks on this as a mathematical result in game theory. This speed minimized the time we spent in the high-risk regions while transiting from MAD to where we were in the 1990s). The Times article says, "The original idea was that modest rebuilding of the nation’s crumbling nuclear complex would speed arms refurbishment, raising confidence in the arsenal’s reliability and paving the way for new treaties that would significantly cut the number of warheads. Instead, because of political deals and geopolitical crises, the Obama administration is engaging in extensive atomic rebuilding while getting only modest arms reductions in return."

FWIW, most Moon landing conspiracy theories claim that Soviets were in on the scam, either because they were bribed (a common theme claims food shipments were the bribe, thereby "explaining" why the USSR didn't have any more devastating famines),

This! Except for:

They're not so great for either the temporary workers or other potential competitors in the labor market, because they are tied until the sponsoring employer *may at its discretion* apply for permanent residence status. Note in this case success is by no means assured, and may take up to two years.

Two years? If you're a lucky one, I suppose that's true. I'm looking at about 4 years right now, and I know some guys from India for whom it's more like 6, and I believe even that's not the worst.

If you get a cataract, spend the extra money on a CrystaLens. Unlike 45 year old natural lenses and implants available before 2003, they will actually focus. Of course they're under patent so they're about a thousand dollars each more expensive than other implants. I'm sure I'll have a cataract in the other eye not too long from now, the last eye doctor I saw said "a couple of years" and it's been longer than that.

I think I'll wait until 2023 when the patent runs out and everybody makes them, the ones like my mom has will be obsolete. I only use that eye to look at tiny things, anyway.

Insurance paid for all but the extra thousand, it was the best thousand dollars I ever spent. The device inside my eye is my favorite device of all.

Did you see the stats for the growth of their middle class over the past 15 years or so?

I'm not disputing that the country is ardently capitalist and has tightly guarded elite circles. But for most people in there, that's not where they are aiming for. What they want is basically just comfortable living, and their standard for it is getting pretty close to what the West enjoys. And with every new generation, there are millions more actually enjoying it - even though there's still hundreds of millions locked out. But for now, the trend is good.

"How are you UPS'ing for 6 hours?"

Sorry I missed the "How" part at first:
Deep cycle motor boat wet batteries coupled to an inverter. Not recommended anywhere for home use but sure cheaper than dry batteries which cost at least twice as much for the same efficiency. I now have two 12 volts batteries and I used to have 4. They are around 100$ a piece and I change them every 6-7 years or so since the power rarely go down around here so they last a long time. Most of the time, they cycle when I simulate a power outage to test the batteries. 1 hour power out test every 2 month and one test until the batteries are drained like once every six months or so.

Use at your own risk, I don't recommend or endorse anything here ;-)

"How are you UPS'ing for 6 hours?"

Yes, I used to use it as an Internet server with live websites and such on it but I have since moved those to a real data center because bandwidth was cheaper. I used to be able to stay up 48 hours on batteries if I shut down the desktop but I have reduced the number of batteries to half what it used to be after moving to a real data center for live sites that need to be up all the time. I also have a small generator that I can use to recharge the batteries but I usually do not bother now. I have to plug and start the generator manually. The desktop is in another room with electrical wiring running to that room. The desktop uses more power than the server because of the 4 screens and video cards. Nice video cards suck a lot of power. One of the desktop screen is a 50 inches TV not plugged into the UPS circuit. I use a USB extension cord for the wireless dongle that allows me to control the playing on the TV with a wireless keyboard and mouse.

Same kind of setup in the real data center, one big server running a bunch of qemu VMs with virtual networks separated by firewall rules.

You must still have enough room to hang clothes and what not in your 42u rack then...

The whole "needles in the eyeball" are just a stepping stone to something truly amazing.

Indeed. I was severely nearsighted all my life, after the cataract surgery I no longer need corrective lenses at all, not even reading glasses and I'm 62. My vision in that eye went from 20/400 to 20/16. Truly a miracle.

BTW, my retina surgeon said that my retinal detachment was a result of being so nearsighted; a nearsighted eyeball isn't perfectly round like a normally sighted person's eyes.

That was the Nixon/Kissinger theory of the 1960s/70s. It was used to cut China all sort of political and economic slack. It was proven wrong by the 1989 Tiananmen Square Massacre.

Was it, though? China circa 1960s/70s was a totalitarian dictatorship where Tiananmen square was an impossibility simply because any dissent would be crushed long before it would get to mass protest stage, and the yearly number of victims was far greater, too. Compared to China after Tiananmen, the latter is far more liberal. It's even more liberal today.

If you want a better China then the US should treat China as China treats the US. Have reciprocal economic and trade policies, punitive measures for egregious behavior, ... No more cutting them slack hoping they will moderate over time, no more treating them like they are an impoverished developing nation,

I did not suggest doing such a thing. The best thing you can do is just trade (and yes, this doesn't preclude e.g. tariffs to even out the price of labor differences, environmental concerns etc).

As Chinese economy grows, so does its middle class. As its middle class grows, it demands more democratic reforms and more government responsibility - ultimately, a way to better China, for both its people and its neighbors.

So if you want a better China, you should do the exact opposite of what you're doing.
