Who authorized the U.S to furnish military supplies to other nations?

The U.S. Congress authorized the provision of military supplies to other nations through legislation such as the Lend-Lease Act, passed in March 1941. This act allowed the U.S. to supply allied nations with military aid during World War II, effectively enabling support without direct involvement in the conflict. The decision was rooted in the desire to assist allies like Britain and China in their fight against Axis powers.
