Why is the US so desperate to have a nuclear arms control deal?
Is it because
a) the US can't afford a nuclear arms race with China, or
b) the endgame for US planners is nuclear war with China, and they want to ensure that China has a limited arsenal of missiles
A) I'd guess. China is way more suitable to out lasting a nuclear apocalypse, because unlike US and similar to USSR, they have hardened electronics across large parts of the country against EMPs, they also have much better disaster relief capability, including bunkers.
Calling back to what I wrote in an earlier post, Russia has been bragging about it's 4 mil shell production, but as I demonstrated, that production rate is simply pathetic compared to China, it's akin to comparing ww2 Italy with USA (in the most literal sense of the word, USA produced more airplanes in ww2 than Italy produced arty rounds, and modern China is able to produce slightly less guided missiles than Russia can produce arty rounds in the same time).
You would rightfully expect that USA can blow Russian production rates out of the water, since they're still the 2nd largest economy, have dollar exorbitant privilege and so on. But for one reason or another, we have not seen US shown clear full spectrum production superiority against Russia. Sure, the production of aircraft in US is much better, but production in rocket powered projectiles and drones lag behind.
That means US maybe does not have the ability to build new nukes "like sausages" anymore, perhaps due to corruption or loss of knowhow. While we have always assumed US is able to do so, they may have fooled the world regarding their true capabilities.
Hence, they seek the farce of "nuclear limitation talks", to avoid being further burdened financially.
I honestly think this is an area China should concede to US, simply because there are better ways to sink American money than making them build dangerous nukes. If America can save money through the nuclear limitation policy, America will still find another way to waste the money. I don't trust them to be able to use the saved money responsibly for nation building, which is good news for China. I'd much rather see billions go into DEI, some oligarch's trust fund, or at least overpriced conventional weapons, than see it go into ICBMs.
