Lend-Lease and Military Aid to the Allies in the Early Years of World War II. During World War II, the United States began to provide significant military supplies and other assistance to the Allies in September 1940, even though the United States did not enter the war until December 1941.
The United States didn’t actually enter the war until the attack on Pearl Harbor in December of 1941. But they did prepare for some time such as their Naval forces by doubling the size of the navy and pushing the lend-lease act by congress. Hope this helps :)
