What are 4 American responses to World War 1?

Four American responses to World War I included the implementation of the Selective Service Act, which mandated conscription to bolster military forces; the establishment of the War Industries Board to coordinate production and resource allocation; the promotion of the Committee on Public Information to facilitate Propaganda efforts that encouraged public support for the war; and the signing of the Treaty of Versailles, which formally ended the war and aimed to establish a framework for lasting peace, despite the U.S. Senate ultimately rejecting membership in the League of Nations.
