Concept note-1: -Congress passed a series of Neutrality Acts in the late 1930s, aiming to prevent future involvement in foreign wars by banning American citizens from trading with nations at war, loaning them money, or traveling on their ships.
Concept note-2: -During the 1930s, the combination of the Great Depression and the memory of tragic losses in World War I contributed to pushing American public opinion and policy toward isolationism. Isolationists advocated non-involvement in European and Asian conflicts and non-entanglement in international politics.
Concept note-3: -U.S. government ordered rationing during WWII to conserve raw materials for the war effort. To help pay for WWII, the U.S. government relied heavily on the sale of war bonds (lends from citizens to help fund the war. Also contributed to the national debt).
