The Lend-Lease Act shifted U.S. foreign policy from isolationism between the world wars by aiding allies in need, contrasting with previous Neutrality Acts.
The Lend-Lease Act represented a shift from the isolationist foreign policy that dominated American politics between the two world wars. This act allowed the U.S. to provide war supplies to Britain and other countries considered vital to U.S. security, aiding them in their fight against the Nazis.
In contrast, acts like the Neutrality Acts of 1935, 1936, and 1937 imposed restrictions on selling arms to nations at war, aiming to keep the U.S. from getting entangled in foreign conflicts.
By passing the Lend-Lease Act, the U.S. moved from a stance of strict neutrality to actively supporting its allies to safeguard its own interests in a changing global landscape.
