Answer:
Congress authorized the sale of weapons and other war materials to American allies under the terms of the Lend-Lease Act. The Lend-Lease Act was enacted in March 1941 and gave the President of the United States the authority to lend or lease military equipment to any nation deemed “essential to the defense of the United States.”
The Lend-Lease Act allowed the United States to provide military supplies to its allies in exchange for payment at nominal rates, with the understanding that repayment would be made after the war. It was a key element of the U.S. strategy in supporting its allies in World War II before its eventual entry into the war.
