Chinese have a tendency to self destruct and become isolationist. The Han people are very racist.
Even in the article, the guys complains about American power projection. What is his people seeking to do now?
If we learn nothing else from history, is the more you learn from others the better off you are.
True...
China has a tendency towards isolationism, because, just like the USA, it has the luxury of being able to be isolationist. China and the USA are probably the only large nations in the world that both have enough local resources to sustain themselves even if outside trade gets cut off and have highly defensible borders that can deter just about any invaders.
If you live anywhere else, isolationist tendencies will get beaten out of you by reality very quickly.
