German–Soviet Axis talks
In October and November 1940, German–Soviet Axis talks occurred concerning the Soviet Union's potential entry as a fourth Axis Power in World War II. The negotiations included a two-day Berlin conference between Soviet Foreign Minister Vyacheslav Molotov, Adolf Hitler and German Foreign Minister Joachim von Ribbentrop, followed by both countries trading written proposed agreements. Germany never responded to a November 25, 1940, Soviet proposal, leaving the negotiations unresolved. Germany broke the Molotov-Ribbentrop Pact in June 1941 by invading the Soviet Union.
