The nazi-Soviet non-aggression pact of 1939 gave Hitler and the nazis the green light to invade Poland and start World War 2. Two weeks later, Stalin's Red Army joined the nazis in dismembering Poland. 

Historian and author Roger Moorhouse has dived deep into this notorious but poorly understood alignment in The Devils' Alliance: Hitler's Pact with Stalin, 1939–1941. He joins the podcast in a two-part discussion of the importance of the agreement between the 20th century's two bloodiest tyrannies.
