Which program was established to assist Allied nations during World War II?

The Lend-Lease program was specifically established to provide military and economic assistance to Allied nations during World War II. Announced in 1941, this program allowed the United States to supply goods, equipment, and services to countries like the United Kingdom, Soviet Union, and China, which were fighting against the Axis powers. The Lend-Lease Act aimed to ensure that these nations could sustain their war efforts without directly committing to battle themselves, reflecting the U.S. policy of supporting allies while maintaining a degree of neutrality before its own involvement in the war.

In contrast, the Marshall Plan, which came later after the war in 1948, focused on the economic recovery of Europe. The New Deal was a series of domestic programs aimed at responding to the Great Depression during the 1930s, and the Axis Powers Agreement does not pertain to assistance programs but rather the coalition of nations that fought against the Allies in World War II. Together, this context reinforces why Lend-Lease is the correct answer, as it directly correlates to U.S. support for Allied nations during the conflict.
