I understand what you are saying and I readily admit that there were spies who converted easily to Soviet collectivism because they did not read Marx critically, and that at the time the U.S. suffered, as it often still does, from a simplistic view of a good guy-bad guy mentality about the world that utterly failed to recognize that both Communists and Fascists represented an authoritarian collectivism whose similarities were larger than their differences.@BrutusofNY what you wrote about colonial or half colonial policy of some European nations, Russia and Japan in imperial China i more or less agree. KMT was right in demanding the end of this policy. But USA did not have very big role in it and not just this they soon saw the influence of Japan as dangerous. Japan's intervention in Siberia ended in early 20' under severe USA diplomatic pressure. But KMT was also aware that international communism became one of the most big dangers or even the biggest already in 30'. Completely justified conclusion. KMT was supported against Japan and against communists from USA, but support was not big enough because of communist inflitration in USA administration of FDR and even Truman to a smaller degree.
KMT also knew that communists are exploiting Chinese anti-imperialist feelings for their totalitarian agenda. Already in 1927 Chiang saw that so called Nanking incident was inspired by communists to strenghten their positions and weaken his. In Nanking foreign interest were attacked, consulates were attacked, vice president of Nanking university an American was killed etc.
My point has consistently been that the U.S., well before FDR was elected had also moved in a collectivist direction with an admittedly milder form of authoritarian impulse - milder due to its cultural traditions - of which FDR was the result and not the cause.
McCarthy too was a result of that authoritarian impulse and not a cause even as his crudeness and emotional impulsiveness alarmed both those re-actively defending FDR's policies and memory as well as legitimate American civil libertarians. But as I pointed out in a previous post, the policies of Woodrow Wilson in 1917 made McCarthyism look like a day at the beach; so that was not really new either.
I am not a fan of either FDR or Truman and my views of them both would make their supporters' hair stand on end. Long before he became Vice President and just after Hitler turned on Russia in1941, Senator Harry Truman announced that he thought Hitler and Stalin should be allowed to bleed each other white. Had Truman's off-the-cuff advice been followed it is my opinion that Europe and America would have been a much better place for it.
Of course the path also implied that the Open Door in China would have probably have gone by the boards as well - and advocates of American Empire had no interest in that whatsoever.
Hitler's biggest mistake was invading Russia in the middle of June. His second biggest mistake was declaring war on the U.S after Pearl Harbor and giving FDR an early Christmas gift.
