The Lend-Lease Act reflected the U.S. strategy of supporting its allies during World War II by allowing the provision of military aid without immediate payment. This act enabled the U.S. to supply the UK, Soviet Union, and other allies with essential war materials, thereby strengthening their capabilities against Axis powers. By fostering economic and military partnerships, the act not only signified U.S. commitment to defeating tyranny but also positioned America as a leading global power, setting the stage for post-war influence in international affairs.
