How did the U.S. aid the allies before joining the war?

Before officially entering World War II, the U.S. aided the Allies primarily through the Lend-Lease Act, enacted in March 1941. This legislation allowed the U.S. to supply military equipment, food, and other resources to countries like Britain, China, and the Soviet Union, helping them sustain their war efforts against the Axis powers. Additionally, the U.S. provided financial support and engaged in diplomatic efforts to bolster Allied cooperation, while also implementing economic measures to restrict trade with Axis nations.
