Passage of the lend lease act in 1941 signaled

The passage of the Lend-Lease Act in 1941 signaled a significant shift in U.S. foreign policy during World War II. It marked the United States' move from a position of neutrality to one of active support for the Allies, particularly Great Britain, against the Axis powers. The act allowed the U.S. to supply military aid to foreign nations deemed vital to the defense of the United States, without requiring immediate payment. This legislation was crucial in providing the Allies with the necessary resources to continue fighting against the Axis powers before the U.S. formally entered the war after the attack on Pearl Harbor later that year.
