The principal issue in a war in East Asia is about controlling the air and sea. If the US and allies lose that, ultimately Taiwan is lost.
Ground combat on Taiwan is moot.
Uh-huh.
Ever think we might want to replace that $84 billion worth of stuff?
And that it might, like, have to be paid for?
And that money will come out of the budget for other things?
