So, Stalin and Mao never intentionally killed Americans. I suppose the Korean War never happened. Would be news to my father, since Mao sent soldiers from China to Korea, and they tried like Hell to kill him, several times, and damned near succeeded. He was pretty familiar with Chinese from another little conflict in the Pacific, called World War II.
Then there's always the USAF pilots who were facing Soviet pilots in Migs supposedly belonging to the North Koreans. I'm sure Stalin didn't send any of the Russian pilots or the advisors to kill Americans. The fact that they flew for North Korea, and managed their radar installations doesn't really mean Stalin wanted to kill Americans does it?
Oh, and exactly when and where did the U.S. kill 23 million Russians?
