Your belief that Communists and Russians played a significant role in American politics during the 30s and 60s must have been transmitted directly into your amygdala by space aliens from Area 51. Surprise! Your tin foil hat did not protect you! 

Did you ever consider politics and reality may have had something to do with influencing our politics? I wasn't alive during the Roosevelt Administration but knew many who were and appreciated his efforts to put the country back to work and the civic works that resulted. (Consider the price of electricity in the Pacific Northwest) I was certainly alive and politically active during Viet Nam however. Everyone was either for or against. Nobody was on the fence. There was no need for the KGB to inflame antiwar sentiment. LBJ and Nixon did that just fine all by themselves.
