Your opinion, not theirs. The CCP has repeatedly promised to "reunify" China. If they can't do that, then they fail the bar they've set for themselves. And they wouldn't be making, and repeatedly reiterating, this promise if it wasn't taken seriously by the Chinese people.
Xi's personal leadership lies on a promise of taking Taiwan in the forseeable future as part of the "restoration" of Chinese power. Anyone who disagrees honestly has no idea about Chinese political circles.
