Marguerite Buber-Neuman, wife of Heinz Neuman, a German Stalinist leader killed in the purges, reported tnat Stalin said "Won't Hitler keep them busy in the west, etc" to her husband in, I think, 1931. I'll provide a quotation when I have a chance to go to a library. Or maybe some reader will... Incidentally, Marguerite Buber-Neuman was one of the train-load of german communists imprisoned in Russia sent to Hitler after the Hitler-Stalin Pact, as a gesture of good will. She survived to tell the tale.
