If they want to, that's up to them. It wouldn't surprise me if China did do something like this.
> Your complete inability to be a fair global hegemon
Hey, (1) I personally am not a global hegemon. (2) I was describing the way things are not how they ought to be. You should work on distinguishing is from ought; if you can't you'll never understand anything.
FWIW I personaslly think a fair bit of US policy is both immoral and self defeating. But, again, that's irrelevant, because as I said, geopolitics isn't a morality play.
> Where are you going to get your silicon chips from if the Republic of China reunifies with the People's Republic of China?
I'm European and I think the EU should be self-sufficient in chips. This is because any polity that isn't won't in the long term be fully independent.
> US wants to play by different rules than everyone else, not sure that works long term.
"The strong do what they can and the weak suffer what they must" is a rule thast's worked so for for all 5000 years of recorded history (with a few counterexamples). Is that lnog term enough for you? Is that just? No. Does it matter (i.e. affect the course of events)? Not usually.
> I hope you're ready for the era of multiple US-hostile nuclear powers.
A world with lots more nuclear powers may well happen, depending on the result of the present Russia-Ukraine war.
