The Japanese launched a surprise attack on the U.S. naval base at Pearl Harbor, Hawaii on December 7, 1941. Over 2,300 Americans were killed and many ships and aircraft were destroyed in the 90 minute attack, which drew the United States into World War II. Rising tensions including U.S. sanctions on steel and oil exports to Japan due to its expansionist actions led to the attack. In the aftermath, the U.S. and its allies declared war on Japan and caused Japan to begin its campaign to build a Pacific empire.
