The Imperial Japanese Navy carried out a surprise attack on the United States Pacific Fleet and its defending Army and Marine air forces at Pearl Harbor, Oahu, Hawaii, at 7:48 a.m. Hawaiian time, Dec. 7, 1941. The day after the attack, President Franklin D. Roosevelt asked Congress to declare war on Japan and called Japan’s act a “deliberate deception.” Congress approved his proclamation, and soon after, the U.S. officially entered WWII.
