The Lend Lease Act was an arrangement for the transfer of war supplies, including food, machinery, and services, to nations whose defense was considered vital to the defense of the United States in World War II.
The Lend-Lease Act, passed passed March 11, 1941 by the U.S. Congress, gave the President power to sell, transfer, lend, or lease such war materials. The President was to set the terms for aid; repayment was to be “in kind or property, or any other direct or indirect benefit which the President deems satisfactory.” Harry L. Hopkins was appointed (Mar., 1941) to administer lend-lease.
