The Nye Committee, formally known as the Special Committee on Investigation of the Munitions Industry, was established in the 1930s to investigate the influence of the munitions industry on American foreign policy and its role in the United States' entry into World War I. The committee's findings revealed that certain businesses and financial interests had profited significantly from the war. This sparked a substantial public outcry and led many Americans to adopt an isolationist stance, advocating against involvement in European conflicts.
The conclusions drawn by the Nye Committee contributed to a growing sentiment that the United States should avoid entanglements in foreign wars, emphasizing the dangers of militarism and the potential for war profiteering to influence government decisions. As a result, the findings significantly shaped public opinion and policy during the interwar period, leading to the enactment of neutrality laws aimed at keeping the U.S. out of future conflicts.
