True, but Joe Stalin was a rabid anti-semite, probably the main reason for his rivalry with Trotsky. To a large degree, Adolf Hitler solved Stalin’s “Jewish Problem” during the first part of Operation Barbarossa.
I just read a biography by the editor of the Stalin archives. Certainly, starting after WWII, Stalin moved towards anti-semitism and, at the time of his death, was seeking to exterminate jews (I think it was called the Doctor’s Plot”). However, I think that most of his career he worked with other jews in the government without any noticeable fights. He often played different factions against each other, but I don’t think that you can find serious, documented anti-Semitism until later in his career.
He certainly had many Jews that he dealt with on a regular basis in his government for a long part of his time in office. And, of course, he had to get along with Lenin and the rest in order to get into the position that he had.
I have several good books by Russians who write convincingly that Stalin from 1948 to his death in 1953 was indeed planning a holocaust for the Jews. When he died Beria immediately terminated such plans. And, by the way, he at the same time released Molotov’s Jewish wife from her internment camp. Stalin’s anti-Semitism wasn’t the old garden variety Russian anti-Semitism. It was definitely of the the genocidal sort. If you guys would like the titles of some of these books I’d be happy to provide them. It’s also a paradox that all Stalin’s formal education was from the Orthodox seminary in Tiflis. Good thing he never was ordained to holy orders in the Russian Orthodox Chuch!
