During the 1930s, the U.S. government attempted to distance the country from earlier interventionist policies in the Western Hemisphere as well as retain an isolationist approach to events in Europe and Asia until the beginning of World War II.
Following World War I, the United States was reluctant to become entangled in overseas conflicts that would lead to another war. The U.S. previously had used the Monroe Doctrine and the Roosevelt Corollary to justify intervention into Latin American affairs. However, the U.S. retreated from these policies during the1930s with the Good Neighbor Policy. Under this policy, the U.S. emphasized cooperation and trade rather than military force to maintain stability in the Western Hemisphere.
By the mid-1930s, signs in Europe and Asia pointed to a new world war. The U.S. passed laws asserting U.S. neutrality to prevent the country from being entangled in a foreign war. The Neutrality Acts of 1935 and 1937 banned export and transportation of arms to nations at war. The Neutrality Acts were attempts to isolate the country from the problems erupting in Asia and Europe.
The U.S. tried to maintain its isolationist approach when war broke out in Europe. But the U.S. aided countries fighting against fascist aggression. The U.S. introduced the “cash and carry” policy, negotiated the destroyer-for-bases deal and enacted Lend-Lease, all of which supported Britain and France in their fight against the Axis powers. The U.S. also helped write the Atlantic Charter in 1941, a document that established goals for the post-war world.
The expansionist policies of Japan and the bombing of Pearl Harbor ended U.S. isolationist policies. The U.S. declared war on Japan on December 8, 1941, one day after Japan bombed the U.S. naval base at Pearl Harbor, Hawaii.
