The attack on Pearl Harbor, a US naval base in Hawaii, was a surprise attack by Japan on December 7, 1941. It lasted two hours, resulting in the deaths of over 2,400 Americans and significant destruction of the US Pacific Fleet. The main reason for the attack was Japan's desire to expand its empire in the Pacific. The bombing of Pearl Harbor marked a new frontier in the United States' involvement in WWII by ending the U.S. policy of isolationism, increasing the nation's fighting spirit, and solidifying the nation’s status as a superpower.
