Hitler called in the British Air Force for help
Excerpt from Jonathan Dimbleby's book Operation Barbarossa On the eve of Nazi Germany's attack on the Soviet Union, Hitler and Stalin concluded a non-aggression pact and carefully pretended that they were going to follow its provisions. However, the differences between the two countries were too great to be reconciled diplomatically. Nevertheless, in November 1940, Moscow made such an attempt: Foreign Minister Molotov flew to Berlin to resolve the brewing Soviet-German conflict in the Balkans.
