December 8, 1941 was the date of the US declaration of war, but in fact the US was at war on December 7, 1941 at about 7:55 AM when the Japanese attacked Pearl Harbor, Hawaii.
This war, while not unexpected, was not the war the US wanted to be in because it was felt that Germany was the greater threat. Hitler didn't declare war against the US until December 11, 1941, in support of his Axis agreements with Japan.
