On the morning of December 7, 1941, Japanese bombers staged a surprise attack on U.S. military and naval forces in Hawaii. In a devastating defeat, the United States suffered 3,435 casualties and loss of or severe damage to 188 planes, 8 battleships, 3 light cruisers, and 4 miscellaneous vessels. Japanese losses were less than 100 personnel, 29 planes, and 5 midget submarines.
The day after the attack, before a joint session of Congress, President Roosevelt asked Congress for a declaration of war against Japan. President Roosevelt’s message conveyed the national outrage over the Pearl Harbor attack by pronouncing December 7, 1941 “a date which will live in infamy.”
FDR expressed outrage at Japan and confidence in the “inevitable triumph” of the United States. On December 8, 1941, the United States declared war against Japan; on December 11 Germany and Italy declared war against the United States.
