"Hitler had broken a pact and attacked."

The immediate reason the USSR joined the Allies was Germany’s invasion of the Soviet Union (Operation Barbarossa, June 22, 1941), which violated the Nazi–Soviet pact. After the attack Stalin had no choice but to ally with Britain (and later the U.S.) to fight the common enemy. (Concerns about Hitler’s power in Eastern Europe and Soviet desires to regain/extend territory were factors, but the invasion was the decisive cause.)
