The military history of the United States during World War II covers the nation's role as one of the major Allies in their victory over the Axis powers. The United States is generally considered to have entered the conflict with the 7 December 1941 surprise attack on Pearl Harbor by Japan and exited it with the surrender of Japan on 2 September 1945. During the first two years of World War II, the U.S. maintained formal neutrality, which was officially announced in the Quarantine Speech delivered by President Franklin D. Roosevelt in 1937. While officially neutral, the U.S. supplied Britain, the Soviet Union, and China with war materiel through the Lend-Lease Act signed into law on 11 March 1941, and deployed the U.S. military to replace the British forces stationed in Iceland.
