Taiwan is not Ukraine. Biden has clearly stated that the US will go to war to defend Taiwan, while he had made it entirely clear that he will not go to war over Ukraine. The fact that Taiwan has been a us ally for decades and the US has strongly implied in the past and now clearly stated that they will defend them matters. The US had never even implied they would defend Ukraine and had no treaty obligation to do so. Also China is not Russia, while it's building a formidable navy, air-force and ground force and may be more capable than their Russian conventional counterparts, their nuclear deterrent may not be enough to deter an American intervention in Taiwan. Their nuclear force is small, and though rapidly growing, currently not enough to reliably threaten the US, the destruction is not so mutually assured in the China US equation.
