Not Stalin's lawyer, but close! I discussed his background a bit in Part 1. He was part of a pro-Soviet faction in the State Department in the early 1940s.
Omigod! I thought we were a couple of generations past the old "Who Promoted Peress," "Who Lost China," "GEN George Marshall the Communist Agent" stuff! Most everybody was pro-Soviet (or at least pro-Red Army) in the 40s (aka WWII). Dean Acheson was a stand-up guy against the communists after 1945. And he mocked Bobby Kennedy's timid argument against attacking Cuba in Oct 62 (Bobby: "But, it'd be like Pearl Harbor!")
