Taiwan WAS a break away state 70 years ago that is an independent country FOR THE LAST 70 years. doesn't matter which ally (US, Japan, whoever) Taiwan had, it is operating as an independent country.
If China attacks Taiwan, they are attacking another country. Just like Russia attacking Ukraine. Doesn't matter what psychobabble a dictator spouts.
