Me worries
It seems to me that Xi Jingping stands to lose about the same amount as everyone else if there is a war with Taiwan and the world - anyone, Xi Jingping, or anyone in China, Taiwan, or the US and its allies, stand to lose their life, and the lives of those they love, if there is war. However, virtually everyone stands to gain nothing - except Xi - Xi stands to gain a lot from war potentially.
I think this is disproportionate incentives, in that sense, and it worries me.
