Final answer:
The Lend-Lease Act in 1941 resulted in the U.S. aiding Allied nations during World War II, ending its stance of non-intervention. Domestically, it spurred economic growth and reduced unemployment. Post-war, it played a role in establishing America as a leading global power.
Step-by-step explanation:
The Lend-Lease Act of 1941 had significant impacts on both the U.S. and the international order. As part of the Act, the U.S. provided aid, including weaponry and supplies, to Allied nations crucial to its defense during World War II, thereby altering its stance of non-intervention. The Act, which effectively ended the United States' pretense of neutrality, saw the disbursement of approximately $45 billion in supplies to such nations as Britain, China, and the Soviet Union.
Domestically, the Act had a transformative effect on the American economy. As the U.S. ramped up its production to meet the demands of the Lend-Lease program, unemployment levels dropped drastically, with a nearly 100 percent boost in productivity and output. This led to almost full employment, with new civilian job creation reaching seventeen million.
The Act also played a crucial role in establishing the post-World War II international order, contributing to the U.S.'s leading role in global affairs. Boosted by surplus trade balance from the exports to the allied powers, the U.S. came out of World War II with a revived economy, emerging as a commanding global player.
