How did the lend-lease act keep America neutral in the early years of world war 2?

The Lend-Lease Act, enacted in March 1941, allowed the U.S. to supply Allied nations with military aid without direct involvement in the conflict. By providing arms and materials to countries like Britain and the Soviet Union, the U.S. supported their fight against Axis powers while maintaining a stance of neutrality, as it did not require American troops to engage in combat. This arrangement enabled the U.S. to bolster its allies and prepare for potential involvement without formally entering the war until later.
