Based on what we know about how the Nazi-Soviet Nonaggression Pact ended, some cartoons of the time depicted the probable consequences of the ending of this pact. And indeed, they were prophetic. Europe was on the brink of another major war.
Joseph Stalin and Adolph Hitler signed a non-aggression pact on August 23, 1939. In the so-called German-Soviet Nonaggression Pact, both countries agreed not to take any military aggression or action against each other for a period of 10 years. The pact only lasted two years because, in 1941, Hitler invaded the Soviet Union.
