The Lend-Lease Act marked a significant departure from American neutrality by authorizing the provision of war supplies to Allied nations during World War II. While the legislation faced intense political debate—gaining support from figures like Wendell Willkie while drawing strong opposition from isolationists like Charles Lindbergh—it proved instrumental in the eventual Allied victory. Historians frequently cite the act as a pivotal strategic decision in the history of American foreign policy.

“A recent survey I did with members of the society for historians of American foreign relations ranked the Lend-Lease Act as the fifth-best decision in U.S. foreign policy history.”

“Lynne, I think most historians would argue that Lend-Lease helped the United States and its allies win the war.”

“If Lend-Lease passed, it would mean that America was no longer neutral. I mean, there could be no pretense of neutrality.”
