Lol wiping them out would be childs play. Go ask any taiwanese why they havent got the balls to declare independence after so many decades. Not a single one of them wanna go to war over politics and die for nothing. They got 0 support from the population over such a move, any idioit can see that otherwise they wouldve already be a nation. They all go back to China, hong kong, macau, no rush really, especially when u already owns them.
