An isolationist pressure group active in the United States from 1940 to 1941, it aimed to prevent American entry into World War II. It amassed a large following, advocating for neutrality and non-intervention based on the belief that American interests were best served by staying out of the European conflict. Prominent members included Charles Lindbergh and Henry Ford, who articulated the sentiment that the nation should focus on domestic issues and defense rather than engaging in foreign wars.
The organization reflected a strong undercurrent of American public opinion that remembered the losses of World War I and questioned the motivations of foreign powers. Its influence was significant, shaping the national debate on foreign policy during a critical period. Though it ultimately failed to prevent the US from entering the war after the attack on Pearl Harbor, it highlighted the deep divisions within American society regarding its role in global affairs and the balance between national security and international involvement.
