Asian people struggle to be better on their own. It’s either they’re bad or the good people are too nice to do anything. If US was to stay out of the region, there would be war, chaos, and a lot of atrocities. I could be wrong…but I don’t know any asian country that is better on its own.
Just look at communism. Look at Germany and the side Russia controlled and the former Soviet Union. Look at N.Korea. Then look at countries like Japan, Taiwan, and S.Korea that sided with the US. If the US didn’t get involve, Europe and Africa would be under control of the Nazis and Asia under Japanese Empire.
