During the early stages of World War II, the British and French Allies made a series of proposals to send troops against the Soviet Union, which had invaded Finland in 1939 as a consequence of the Molotov-Ribbentrop Pact. The plans involved the transit of British and French troops and equipment through neutral Norway and Sweden. The initial plans were abandoned due to Norway and Sweden declining transit through their land, fearing their countries would get pulled into the war. The Moscow Peace Treaty ended the war in March 1940 precluding the possibility of intervention.
