Major Japanese tactical victory; precipitated the entrance of the United States into World War II

The attack on Pearl Harbor, also known as the Battle of Pearl Harbor, the Hawaii Operation or Operation AI by the Japanese Imperial General Headquarters, and Operation Z during planning, was a surprise military strike by the Imperial Japanese Navy Air Service against the United States naval base at Pearl Harbor, Hawaii Territory, on the morning of December 7, 1941. The attack led to the United States' entry into World War II.

Japan intended the attack as a preventive action to keep the U.S. Pacific Fleet from interfering with military actions they planned in Southeast Asia against overseas territories of the United Kingdom, the Netherlands, and the United States. Over the next seven hours there were coordinated Japanese attacks on the U.S.-held Philippines, Guam and Wake Island and on the British Empire in Malaya, Singapore, and Hong Kong.
