How did the U.S. increase support for the war effort?

The U.S. increased support for the war effort through various means, including the implementation of the Selective Service Act, which instituted a draft to enlist soldiers. Additionally, the government ramped up production of war materials by mobilizing industries and establishing agencies like the War Production Board to coordinate resources. Public campaigns, such as war bond drives and Propaganda, encouraged citizen participation and financial support. Rationing of consumer goods further helped to prioritize resources for the military.
