The United States gradually moved away from neutrality in the period following Japan's attack on Pearl Harbor in December 1941. Prior to the attack, the U.S. had attempted to remain neutral in the conflict, providing aid to the Allied powers without actually entering the war. However, the surprise attack by Japan led to a change in public opinion and a call for action. President Franklin D. Roosevelt gave a famous speech to Congress in which he declared that the attack on Pearl Harbor was a "date which will live in infamy" and requested a declaration of war against Japan. In response, Germany declared war on the U.S. on December 11, and the U.S. entered the war on the side of the Allies.
After entering the war, the U.S. took a more active role in the conflict, providing troops, supplies, and resources to the Allied powers. The government also implemented various measures to support the war effort, such as rationing and price controls. These efforts were successful in mobilizing the country for war and helped to bring about an Allied victory.
Overall, the U.S. gradually moved away from neutrality in response to the attack on Pearl Harbor and the country's desire to take action in the face of aggression by Japan and Germany. The government's efforts to mobilize the country for war were successful in helping to bring about an Allied victory and establish the U.S. as a world power.
