So the Chinese want to create the Borg? Not a bad idea.
It is a bad idea. The best survival of any race depends on it's limited differences. Neither homogenity nor having completely different race wouldn't work out. Homogenous entities looks easier to manage and sounds cool, but when a epidemic strikes, they are the first to vanish.
Dude.. i am responding to your question why China shouldn't be given a free hand to conquer entire east asia. I am giving assumptions with a what if to your what if question. I am not saying that it already is (although it is already behaving like one). Do u need a more bigger proof when China is trying to claim the 3/4th of the sea which they don't control?? It is pretty obvious to any sane person that it is already moving in the direction of trying to grab more and more territory. Their 'Realistic' policy is far from reality. We don't need to learn from Chinese. We just have to turn their stupidity into our opportunitiesExactly which country is China trying to "engulf and annex"? Taiwan?
The Chinese mindset is in tune with how geopolitics work. They have learned from the Westerners who came before them, and we in turn should learn from them. Their mindset is not "medieval" but rather realistic.
