lend-lease

lend-lease, system by which the United States aided its World War II allies with war materials, such as ammunition, tanks, airplanes, and trucks, and with food and other raw materials. Pres. Franklin D. Roosevelt had committed the United States in June 1940 to materially aiding the opponents of fascism, but, under existing U.S. law, the United Kingdom had to pay for its growing arms purchases from the United States with cash, popularly known as cash-and-carry. By the summer of 1940, the new British prime minister, Winston Churchill, was warning that his country could not pay cash for war materials much longer.

In order to remedy this situation, Roosevelt on December 8, 1940, proposed the concept of lend-lease, and the U.S. Congress passed his Lend-Lease Act in March 1941. This legislation gave the president the authority to aid any nation whose defense he believed vital to the United States and to accept repayment “in kind or property, or any other direct or indirect benefit which the President deems satisfactory.” Though lend-lease had been authorized primarily in an effort to aid Britain, it was extended to China in April and to the Soviet Union in September. The principal recipients of aid were the British Commonwealth countries (about 63 percent) and the Soviet Union (about 22 percent), though by the end of the war more than 40 countries had received lend-lease help. Much of the aid, valued at $49.1 billion, amounted to outright gifts. Some of the cost of the lend-lease program was offset by so-called reverse lend-lease, under which Allied nations gave U.S. troops stationed abroad about $8 billion worth of aid.
