Great Britain and France (green and blue) asking Joseph Stalin (black) to join their fight against Germany. The Soviets didn't trust the Western countries. These Western countries feared their communism. The Soviets required the independence for Baltic States, but they denied because Germany would be able to move into their countries during attacks.
Negotiating with Stalin
Will you join us?
During this time, Hitler (brown) and Stalin were secretly creating the German-Soviet nonaggression pact. This pact stated that Germany and Russia would never attack each other and they would stay neutral if one went to war with the Western countries. Hitler did this so Russia would not join Great Britian and France. Russia did this so they could have enough time to prepare for war with Germany because they had other problems.
The Nazi-Soviet Pact
Let's make a secret pact!
That could help me...
Secretly, Hitler and Stalin divided up Europe. Russia was going to take the Baltic countries, while Germany was to take Western Poland. This secret agreement made Germany very strong, Russia was neutral in the war, which lost the Western nations a powerful ally.
