Answer :
Hitler and Stalin agreed to a non-aggression pact in their secret Nazi-Soviet pact.
In the secret Nazi-Soviet pact, also known as the Molotov-Ribbentrop Pact, Adolf Hitler's Germany and Joseph Stalin's Soviet Union agreed to a non-aggression treaty.
The pact, signed in August 1939, included a secret protocol that divided Eastern Europe into spheres of influence, effectively allowing both powers to expand their territories without interference from each other.
This agreement provided Hitler with assurance that the Soviet Union would not intervene in his plans for expansion, while Stalin sought to secure territorial gains and buy time to strengthen the Soviet military.
However, the pact was short-lived, as Hitler eventually broke the agreement by launching Operation Barbarossa, the invasion of the Soviet Union, in June 1941, leading to a dramatic shift in the dynamics of World War II.
