Hell, we've got genuine believers (...or shills) even in these comments talking about how US support for Taiwan is all just a ploy to weaken China.
If Xi makes a move on Taiwan, he turns China into a Russia-like pariah to the West and bears an immense cost in lives and materiel. For what gain exactly?
Taiwan is worth more as a bogeyman he can point to for nationalistic rallying than as an actual possession.
