After the August 23, 1939 Molotov-Ribbentrop (Non-Aggression) Pact, the Soviet Union, helped Hitler invade Poland, invaded Finland, threatened the 3 Baltic States (Estonia, Latvia, Lithuania), Hungary, Bulgaria & Romania. The Soviet Union "joined" the Allies only because it was attacked by Hitler's Germany on June 22, 1941. Before that time, it was a willing ally & supplier of Germany.
