As much of a pacifist I am in real life, sometimes a fight is needed to make things better.
Same could be said for countries and war. Wars are generally terrible, but if it saves more lives than it takes, then it is worth it. I support space exploration very heavily and the science involved with it. Most of the science would not have been possible without the Cold War.
Talking things out with China will probably lead to millions of deaths due to their regime, and then the war would come anyway after so many years.
