Im reading The History of the KGB. Its is from a guy named Mitrohkin who was a KGB archivist. The FDR administration, the lefts icon, was riddled with Soviet agents. The book names names and describes how indifferent FDR and his people were to the knowledge they had been penetrated...
I read it in stupefied disbelief. Walter Krivitsky was assassinated by Soviet agents in a Wshington D.C. hotel room in 1941. Since 1918 or so he had been chief of Soviet Military Intelligence in Western Europe. While he did testify before the House Unamerican Activities Committee, the FBI didn't even bother to interview him! It's a fascinating look into Stalin's atrocities by a man who was an eyewitness and participant. It's also a blood-curdling account of the state of American denial about the true nature of Soviet Communism.
