The Japanese attack on Pearl Harbor is the main reason why the United States entered World War 2. On December 7, 1941, the Japanese launched a surprise attack on the U.S. naval base at Pearl Harbor, Hawaii. This attack led to the death of over 2,000 Americans and caused extensive damage to the U.S. Pacific Fleet. As a result, the United States declared war on Japan the following day, December 8, 1941. The attack on Pearl Harbor compelled the United States to enter the war and join the Allied forces in their fight against the Axis powers, which included Japan, Germany, and Italy.
