PLEASE read post #76 at the FR thread link in my tag line.
After reading those quotes of leaders from 1900 on, THEN tell me whether you believe the CIA did no such thing, or not.
Surely you do not intend to suggest that the CIA was helping Chi-Coms during the 1930s?? ;-)
During W.W.II, the US provided "Uncle Joe" Stalin with many $billions in military aid, and Chinese nationalists (even before Pearl Harbor) with many $millions in aid -- tens of thousands of tons, according to the source above.
I'd suggest that any aid provided directly to Chi-Coms was relatively miniscule.
