On December 7 1941  the United States finally entered World War II. As President Roosevelt said, “…the United States of America was suddenly and deliberately attacked by naval and air forces of the Empire of Japan.” Around 7:55 on a peaceful Sunday morning , 360 Japanese war planes descended from the clouds for a surprise attack against the American naval war fleet at Pearl Harbor, Oahu. 

The Japanese destroyed 5 battle ships, 3 destroyers, 7 regular ships, and 200 American aircraft. There were around 2400 Americans killed and 1200 wounded  from Japaneses aircraft fire,  torpedoes, bombs and kamikazes.The Americans took out 5 Japanese midget submarines, 30 aircraft and just about 100 men .

The next day President Franklin d. Roosevelt gave his famous “infamy” speech to congress. This speech was said to acknowledge that the United States of America was attacked and is now in a state of war with Japan . The US Senate ended up voting 82 to 0 and the House of Representatives 388 to 1 to join the war and fight. Soon after this two other world powers, Germany and Italy, declared war with  the United States.
