The Moscow Party Line before the German invasion - July 20, 1941, as I remember - totally supported the Germans and said that the British were doomed. With the invasion this Line changed almost overnight. Those Americans whose views change from pro-axis to "anti-fascist" after 7/20 were following the Moscow Line. Old Joe was one of them.
There is an old GRU man who writes as "Suvorov" that tells a story that confirms my opinion about Kennedy. There was a huge agent in the US whose identity was totally secret and who was at the center of the US government. Look at the forced retirement of James Jesus Angleton. There is a lot more. Not legal proof, but a huge red flag from a counter-intelligence point of view.
You got that right. The Pro-Nazi's in Americas were that way as laon as Berlin and Moscow were Allied. As soon as the Germans invaaaaded Russia their tune changed.
They used the Pro-Nazi stnace to cover for their Communist beleifs.
