I mean the basic premise is that the bottom line for control is deadly force.
Maybe there really is no alternative but I think it's worth mentioning that as long is that is the operating mode, there is no real security for human life. You can certainly have extended periods without major wars but as long as the paradigm remains, it's always just a matter of time before the next mass killing starts.
I mean as far as Taiwan goes, it's right next to China, there is a long history. The paradigm is that you have a right to whatever you can take by force. If they get to the point where they can invade successfully and don't think that it is _actually_ going to start WW3, they may feel obligated to do it. Because yes it would probably result in a large loss of life, but the international operating mode is that serious conflicts are resolved with machines designed to destroy property and lives.
