Abruzzi City for The mobilization of 3,000,000 U.S. troops invigorated the war effort and helped to bring Germany to terms. Although the country was only actively involved for 17 months, the American contribution changed the course of history. Within the country, the powers of government changed almost overnight. New government agencies were created to handle different aspects of the war, and each of them had powers over resources that changed the lives of the American people. While most agencies were dismantled after the war, the role of government and the public’s perceptions of its role had changed immeasurably. Abruzzi City 2016.
