Who was the prominent U.S. politician associated with revealing corruption related to arms manufacturing prior to WWII?

The prominent U.S. politician associated with revealing corruption related to arms manufacturing prior to WWII is Gerald Nye. In the 1930s, he chaired the Senate Nye Committee, officially known as the Senate Munitions Committee. This committee investigated the influence of the munitions industry on American foreign policy and examined the financial dealings of arms manufacturers. Nye's work highlighted how profits from war materials could drive nations towards military conflict, contributing to public skepticism about U.S. involvement in foreign wars and shaping the isolationist sentiment of the era. His findings were crucial in understanding the military-industrial complex and its implications for American politics and policy. This context underscores the significance of his role in this investigation during a period when the United States was grappling with the ethical implications of war and the power of corporate interests in American government.
