I'm not overly concerned about China defending itself from conventional US attacks. I'm much more concerned about the risk of the US opting for nuclear strikes. Because if the US loses thousands of men, and unacceptable quantities of warships and airplanes. I don't trust the unhinged American leadership to not consider nuclear retaliation on Chinese industrial zones, which are in the major cities. Especially the more crazed Republican-aligned warmongers, who think that nuclear war with China is 'winnable'. That is why, China's nuclear deterrence must play a much bigger role now, more than ever.
I like your post. Good thinking. But I have a different opinion regarding US opting for Nuclear Strike against China.
I don't think that US will ever opting for a nuclear strike against China. Not only because China can retaliated. But it also will destroy the purpose of why United States antagonize China to begin with.
Now, look at what is United States objective to China?
1. They want to defend their hegemony status, with everything they got.
2. To weaken China economically, and to prevent China from take over their place as the hegemon.
Basically, US wants to defend their hegemony status, and to prevent China to become the next Hegemon. But if they opting to use nuclear strike against China, then it will go straight for US to lose their hegemony status. Why?
Simply because a nuclear exchange with China will make US unable to left unscathed. It will destroy their economy for sure, as their cities, etc will also become a radiated ruins. At that time, not only China, but US will also become poorer faster than anybody else. And it will give a huge benefit for another country to replace them as the next hegemon on our Earth.
So nope, opting to use Nuclear Strike will not give any benefit to United States. Rather than nuclear, US will try with their best to surround China, and bait China to be trapped into a prolonged war, like Russia in Ukraine. But their only option is Taiwan. So they will do whatever they can to bring PLA to Taiwan, so China will lose their economy and industrial power, because of the war.
But it seems, rather than China, it is them who got trapped in Ukraine right now. It is because they have a new obligation that force them to pay the war at the scale of Ukraine war. I they're not careful, the war will affect their economy in the long run. And China, a neutral country can produce more wealth than US. Simply because they don't have any obligation to pay for the war.
