China benefits from the global nuke stockpile lessening because when there are comical amount of nukes, even having an edge in tech becomes irrelevant in the face of nuke spamming.Nope, can never trust USA
Nope, can never trust USA... China must do the only thing it can do, increase its own nuke count and delivery capabilities
Ideally, China's enemies should be controlled into having nuclear stockpiles similar to India or Pakistan, I.e. ones that can be defeated by China if it should come to the worst, while China retains a stockpile of similar or slightly larger size, except it is fully orbitalized and HGV ready.
China will probably not achieve this goal with USA through negotiation only, but I don't see why China shouldn't send a rep over to USA to ask them to go down in nuke numbers together. Worst case, US refuses and China can play it up as American nuclear irresponsibility.
