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).
