WORLD HISTORY

Detailed explanation-1: -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.

Detailed explanation-2: -The destruction and cost of WW1 had left their mark on America and the majority of Americans wanted to be kept out of any future involvement in European politics and simply wanted to be left alone to concentrate on building prosperity in the United States.

Detailed explanation-3: -The US was isolationist in the period leading up to World War II even while moving to become more involved once war broke out. It was the Japanese attack at Pearl Harbor that brought the US into the war. The US has been isolationist at other times, with the main example being the US neutrality during World War I.

Detailed explanation-4: -President James Monroe’s 1823 annual message to Congress contained the Monroe Doctrine, which warned European powers not to interfere in the affairs of the Western Hemisphere.

Detailed explanation-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.

Detailed explanation-6: -Thus, U.S. foreign policy during the 1920s was characterized by the enactment of isolationist policies; for instance, the U.S. opted not to join the burgeoning League of Nations, even though it had been the nation to first propose such international cooperation.
