If you define "China" as being larger than any political party, what is wrong with America's presence? What were we there for? Hint: It wasn't to fight Communists. That came later.
We were there fighting the Japanese.
The problem with your thinking is that it assumes that only a Communist Party Chinese is a real Chinese.
You see, the CCP only cared that THEY ruled China. Nothing else mattered/s. They could care less about Japanese. The CCP were a bunch of lying two bit propagandists who never fought the Japanese they hate so much.
They were/are defining "China" around themselves and their party. America on the other hand was not.
You would have fit in to the Red Guards just fine with that kind of thinking.
