De-facto Blockade (General)
And I would add that I think the US will likely abandon Taiwan rather than wage all out war with China. It might put up a token fight,one that nobody would confuse with anything seriousness enough to lead to nuclear war. But I think there's a very good chance that the US will let China have Taiwan.
But, they'll use that as leverage to increase military positions in East Asia, particularly the Philippines, which they'll try to reestablish bases in, and Pacific Island nations, Australia, etc.
I hope none of that happens. But what would a war between China and the US look like? I mean, seriously, what would be the outcome of that? How would it be resolved? And could it be resolved without going nuclear?
This is why the status quo is just fine!
