Also the US has very publicly shown they don’t have the ability to effectively wage war over any period of time.
Yes and no. The Iran war is deeply unpopular and won’t even pass congressional approval for money. It’s being fought from pocket change budgets because they know they can’t pass a funding bill for it. Also not the same kind of war. Any period time? US waged war for 20+ years in Afghanistan. Pretty effectively! To what end? Not an end an army can really achieve so… there you are. But a war that might actually be popul…
That was an occupation and a low intensity “pacification” mission. Waging a prolonged war against a military peer on the other side of the continent is a bit more problematic (considering that US is/was on the brink of running out of advanced weaponry in Iran despite having aerial superiority which they won’t over Taiwan, Japan would have to get involved as well cause otherwise US would have to entirely rely on the fragile carrier fleet).
Using tactical nukes (even regardless of the extreme geopolitical downsides that might bring) wouldn’t necessarily give a great tactical advantage either, unless they are willing to do that over Taiwan itself to destroy the landing forces).
