How did the Lend-Lease Act impact the United States' involvement in World War II?

The Lend-Lease Act allowed the U.S. to provide military aid to countries like Britain and the USSR, which promised to repay the aid after the war. This significantly increased U.S. involvement in the war before the country officially entered as a combatant.
