China will not use nuclear weapon first, at least not strategic one.If China did want to use a first strike, it would be most foolish to make others believe that they would do so. Isn't the whole point of a succesful first strike based on surprise?
I am really confused right now, what does it mean that China can make US wasting its resource on these useless bomb? Because AFAIK US is not going to massively expand their nuclear arsenal accordingly no matter whether China has more nukes. And BTW how would China convince US that its nuclear deterrence is insufficient therefore commit more money into nuclear money printers if China is unwilling to disclose the true size of its nuclear force and intention?If you reread what I wrote, China doesn't threaten to nuke conventional attacks in order to keep US invested, the same way US kept the USSR invested.
If China decide to revolve it's defenses around nukes, what would happen is that US would choose a neutral arena to fight for, putting all it's strength into overseas proxy wars. That's significantly worse for China than having 90% of US capabilities tied down because they need to threaten the homeland, yet at the same time the US doesn't have enough power to break the Asia line.
If one looks down through the history, US media and government never took Chinese nuclear threaten serious until it is now serious enough for STRATCOM to re-think their strategy but public view from US is still "only Russia and US has nuclear parity." and Chinese mouthpiece influencers even cohort the idea that "US has 6,000 nukes meanwhile China only has 300."
It is to deter US from attacking China in the first place not fight a real war with US in a conventional way. So China has to make it clear to US counterpart that USN can't neither win the regional war conventionally nor can win the regional tactical nuclear war. To demonstrate this point, China need to make clear that it has enough nukes to put unacceptable loss upon US homeland even withholding a first strike, then it has enough tactical nuclear weapons to blow off US bases in West Pacific if attacked.Isn't it obvious? They will use conventional weapons in greater amounts on US vessels.
China doesn't benefit from starting MAD when you know, they have a lot of other interests that are going well.
Defensive lines work for China because it's a country of 1.4 billion (as much as the cumulative west) that has access to more resources than the western world.
Where would China go on a military offensive? The middle east? That would be US' home arena, militarily speaking. However, now because US has to split it's attention, the middle east is falling to China, not through military means but covert and diplomatic means.
This is the safer way to fight a cold war. Keep the other side heavily invested in the possibility of turning it all with ww3, and then keep piling on proxy conflicts.
Convincing your opponents that you have the ability to end the world at last resort is the safest way to keep the cold war remain in cold not hiding the doomsday machine from the public. DETERRENCE is show of force not use of force.
