IMO, China will get back Taiwan without firing a single shot, the US is slowly de-risking itself from it and will eventually make Taiwan redundant. After seeing how the US is "helping" Ukraine, will the Taiwanese think fighting an all-out war with allies like this is worth it? China doesn't have the same genocidal intentions russia has towards Ukraine, so less reasons for people to fight it out
Edt: would love some arguments instead of downvotes
