What precedent was set by Presidents Wilson and Roosevelt during the two World Wars?

Presidents Woodrow Wilson and Franklin D. Roosevelt set important precedents in U.S. foreign policy during the two World Wars by expanding the role of the federal government in mobilizing the economy and society for war efforts. Wilson's leadership during World War I emphasized internationalism and the establishment of the League of Nations, advocating for collective security. Roosevelt, during World War II, implemented broad wartime measures, including the Lend-Lease Act, and played a significant role in shaping post-war international relations through institutions like the United Nations. Both presidents established a precedent for active U.S. involvement in global affairs and emphasized the need for cooperation among nations in addressing global conflicts.
