I'm not so sure I would bet on it. I think China would rather "reunite" without force, but Xi has put his personal imprimateur on "reunification". Nothing gets people to forget about economic anxiety like a good old-fashioned patriotic war. At this point, I think a lot of it is bluffing- better to have the Americans give up on defending Taiwan without a shot being fired. Better to make the Taiwanese think that "reunification" is inevitable and forget about notions of freedom.
