Concept note-1: -When WWI began in Europe in 1914, many Americans wanted the United States to stay out of the conflict, supporting President Woodrow Wilson’s policy of strict and impartial neutrality. “The United States must be neutral in fact as well as in name during these days that are to try men’s souls.
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: -As World War I erupts in Europe, President Woodrow Wilson formally proclaims the neutrality of the United States, a position that a vast majority of Americans favored, on August 4, 1914.
Concept note-4: -Franklin Roosevelt, pictured giving a radio speech, declared the United States would remain neutral in the war in Europe. Within days of the outbreak of the war, Roosevelt asked Congress to remove the arms embargo provisions from the Neutrality Acts.
Concept note-5: -Isolationism is a political philosophy advocating a national foreign policy that opposes involvement in the political affairs, and especially the wars, of other countries. Thus, isolationism fundamentally advocates neutrality and opposes entanglement in military alliances and mutual defense pacts.
