There was a substance called FOGBANK. This is an aerogel used in thermonuclear bombs. It used acetonitrile in its construction. When absorbed into the body, acetonitrile metabolizes into hydrogen cyanide.

All of the records for making FOGBANK were destroyed. Too many workers were being poisoned by the stuff, so rather than pay out worker's comp and wrongful death lawsuits, the records were eliminated. As an aerogel, the stuff is brittle, crumbles and fractures. When the warheads needed to be reconditioned, it turned out that the limiting factor was the lack of FOGBANK. It turned out that some mysterious contaminant was needed to give it the exact properties necessary. So it had to be re-invented.

To address your other points, China's nuclear position has never been Mutually Assured Destruction - they've only wanted enough warheads to deter the opponent. In the past, this has meant about 200 warheads. Since the US has been developing anti-ballistic missile technology, that means China needs more warheads and more missiles to guarantee a sufficient deterrent. Only the US & USSR built so many nukes that the START treaties were even necessary.

> But the US no longer manufactures nukes

Yes we do.

Final assembly (and disassembly) is at Pantex in Amarillo, TX. Parts are made elsewhere, some in Kansas City, some at Lawrence Livermore, some at Y2. There have never been "production lines". All of them were built as individual projects. All of them authorized and approved by Congressional oversight.

> But what if?

But what if I get a pony?

How many countries has China invaded? How many have the US invaded? How many has Russia invaded? China may be run by buttheads, but I don't see them attacking others. Not like We The People have attacked and invaded.

They are quite willing to attack others.

Just looking at the number of wars that the PRC has been involved in:

1950 : Invades and Annexes Tibet

1950 - 1953 : Assists North Korea and invades South Korea

1954 : Attempted to invade Taiwan

1958 : Attempted to invade Taiwan

1962 : Sino-Indian War

1967 : Nathu La and Cho La clashes

1979 : Sino-Vietnam War

2017 : China-India border standoff

2020-2021: China-India clashes

You also claim that FOGBANK records were destroyed to cover up for lawsuits, Wikipedia does not have anything relating to that. >Manufacture involves the moderately toxic, highly volatile solvent acetonitrile, which presents a hazard for workers (causing three evacuations in March 2006 alone).

Acetonitrile may be poison but has been used in public product very recently: >It has been used in formulations for nail polish remover, despite its toxicity. At least two cases have been reported of accidental poisoning of young children by acetonitrile-based nail polish remover, one of which was fatal.[23] Acetone and ethyl acetate are often preferred as safer for domestic use, and acetonitrile has been banned in cosmetic products in the European Economic Area since March 2000.[24]

Acetonitrile is used on an almost daily basis by anyone doing HPLC (high-performance liquid chromatography). Big 4L jugs of it. The price has gotten exorbitant though and some have switched to using mostly methanol. I don't know what this guy is talking about with the toxicity, it smells kind of nice and has a very benign label. You don't even need to wear a respirator or anything to use it.

China has also de facto militarily annexed territory larger than France in the South China Sea; territory that very clearly belongs to other nations. It was an act of war, they used their military to invade and take the territory of their neighbors.
I mean, China basically said it would go to war to conquer Taiwan. China just fired missiles over Taiwan and into Japanese territory a few months ago. Seems like they're advertising a willingness to attack; why don't you believe them?
The really tricky part about Taiwan. Politically I mean, is that it is not another country, it literally is china.

A history lesson the chinese empire fell apart in the early 1910's, there was fragmentation until it was sort of reunified in the late 1920's the communist's fought the reunified government in the thirties, paused for WW2 and were successful against the government in the 1940's. the pre-communist government still exists on the island of formosa(taiwan)

Now it is hard to say which government is more legitimate. The national government only really had ruled for 10 years at that point and by all accounts I have read they were sort of a shitty government. taiwan appears to be doing ok nowadays but remember that it ran under a military dictatorship until the 1990's

Taiwan at this point would probably be fine relinquishing their claim to the chinese mainland. but the communists do not want to let them go.

My only real take away from all this is that the chinese are there own worst enemies, what the japanese did to them in mancheria was brutal, far worst than the holocaust. What the chinese did to themselves afterwards was even worse.

>My only real take away from all this is that the chinese are there own worst enemies

I have a pet theory that almost every group of people is their own worst enemy.
