I am well aware of that. And the fact that along the coast and major cities, Japan did not really occupy that much of China. And we were supporting the Nationalist Chinese, and even the Marxists put things at rest until the Japanese were taken care of.
In fact, we also helped a great many Marxists during that war. Seeing Japan as the larger threat. Even giving supplies and advisors to both Mao and Uncle Ho.
Yes, I am very much aware of China at the time, and in the over four decades before as well. But all you seem to be able to do is try to throw darts over and over, but none of them seem to stick.
