Answer 2

Answer:

Although the war began with Nazi Germany's attack on Poland in September 1939, the United States did not enter the war until after the Japanese bombed the American fleet in Pearl Harbor, Hawaii, on December 7, 1941. World War II began in Europe on September 1, 1939. For more than two years the United States remained officially neutral in the conflict, and Americans debated whether to stay out of the war or to join the Allied forces fighting Nazi Germany.Some interventionists believed US military action was inevitable, but many others believed the United States could still avoid sending troops to fight on foreign soil, if only the Neutrality Acts could be relaxed to allow the federal government to send military equipment and supplies to Great Britain.
