The effect of the attack of Pearl Harbor was that it forced the U.S. into a war with Japan; a war that ended in the unleashing of the worlds first, and hopefully last, use of a nuclear bomb in an attempt to defeat an enemy.

The attacks-from troop landings at Kota Bharu, Malaya, to the air attacks ranging geographically from Hong Kong to Pearl Harbor-took place over seven hours.
