Starting in 1933 with the [[World Economic Conference]], American public opinion and national policy was to minimize the risk of entering another war by isolationist laws, such as the Neutrality Laws. President [[Franklin D. Roosevelt]], started in late 1937 to reverse the isolationist policies. When [[World War II]] began in late 1939, the U.S. was officially neutral but gave significant military aid to Britain, France, and China. It was only after the bombing of [[Pearl Harbor]] in December 1941 that the United States abandoned its isolationism and entered the war. See [[America First Committee]] for the 1940–41 debate on avoiding American entry into [[World War II]] in Europe. | Starting in 1933 with the [[World Economic Conference]], American public opinion and national policy was to minimize the risk of entering another war by isolationist laws, such as the Neutrality Laws.
