By December 1940, Great Britain had run out of funds to fight the war. Roosevelt proposed the Lend-Lease Act, which allowed the United States to lend or lease arms to any country considered “vital to the defense of the United States.” Britain could receive weapons, then return them or pay rent for them after the war. Congress passed the Lend-Lease Act by a wide margin. Lend-lease aid eventually went to the Soviet Union as well, when in June 1941, Hitler invaded the Soviet Union. Roosevelt followed Britain’s lead in supporting any state fighting the Nazis.
