A nuclear war will realistically never be won by any side.Then China better speed up its nuclear modernization. The West maintaining nuclear superiority over China in a time like this is not acceptable. Build a few thousand weapons and their delivery mechanisms, and then see what happens to Western resolve.
And in what way does the west have nuclear superiority anyways? I guess they have better undersea missiles. Yet China has better land based missiles and FOBS. China is also likely ahead in missile defense. Both sides have enough early warning that they will see an attack incoming.
Undersea missiles were king in the early and mid cold war because ranges of missiles were poor and early warning was weak. Nowadays, the only nuke which cannot be early warned against would be a FOBS. Heavy land icbm such as DF5, DF41 and Sarmat can reach globally from the nation of origin.
If America is truly desparate they will invade regardless of nukes. Nukes protect the mainland but just like if China invaded Okinawa, Guam or the rest of the Pacific Islands, US would not be able to justify nuclear ultimatum because the territory is not central enough, so can US invade islands in the SCS and Taiwan without invoking a realistic nuclear ultimatum.
The only nuclear option that would work is making the warhead delivery so fast and the missile defense so powerful, that China can do to America same as what they can do with India, I.e. strike them first out of nowhere, shoot down every return shot and then tank the sporadic hit on the chin using bunkers.
But the difference is that India possess 30 dangerous ICBMs while America has over 2000. The tech doesn't exist now and likely will not exist.
