It’s useful to sit back and think about things like this from a perspective of goals.
China has built and is building semiconductor foundries all over the mainland. There is no reason for them to leave Taiwan’s semiconductor base intact.
Bombings and missiles to destroy it all would do what? Eliminate the source of western interest. Then China can sit back and not invade and just go on with life.
Western interest would soon move on. Taiwan might then vote to unite with the mainland.
The point being, when you are dealing with self sufficient entities, the question “what does who have that they might want” is very tricky. Taiwan has nothing China might want, other then historical precedent. That is actually weak. Chiang Kai Shek’s wife persuaded Congress that it was Chinese land — when less than 10 years prior the Japanese had owned it (for decades) and used it for POW camps during WW II.
Think about your own post.
Did Japan stop at the Chinese mainland during their expansionist period?
Lol.
