True, but by the same token the West (and the rest of the East, and the world) has no economy without China. It makes everything higher stakes for everyone involved.
> * Taiwan is an island. Invading an island is a much harder task.
Also true, but supplying a small island is also much harder than supplying a country with a large contiguous land border with you/your allies. All but one of Taiwan's major ports lie on the strait. And since Taiwan is much smaller than Ukraine, it has less strategic depth than Ukraine; there's nowhere for Taiwanese troops to fall back to.

I'm increasingly convinced that China's first act of war won't be shipping troops to the beaches but a blockade. That then presents the US with an unenviable choice: escalate to a full on shooting war to break the blockade, or give control of Taiwan's imports/exports (which is to say, Taiwan) to China.
