The bombing of the U.S. naval base at Pearl Harbor by Japan on December 7, 1941, forced the United States to enter World War II and permanently ended its policy of isolationism. Prior to this event, the United States had tried to avoid involvement in global conflicts and maintained a neutral stance. However, the attack on Pearl Harbor made it clear that the country could not remain isolated and had to take an active role in international affairs.
