My knowledge of the work being done in the Soviet archives is limited, I could not make a contributition on this topic. When PBS ran its documentary on the new disclosures resulting from the research that has been done I had a real laugh. The Rosenbergs and Hiss were indeed spies for the NKVD, McCarthy was right when he said there were Communists in the State Dept and Gus Hall was getting a regular cash payment from Moscow. Soviet documents prove that they not the Nazis killed the Polish officers at Katyn. It can't get better than this.
