December 7
Japan attacked Pearl Harbor. The American commanders at Pearl Harbor naval base had received a war warning from Washington that American intelligence had decoded. But Hawaii was not mentioned as a possible target, so the surprise attack on Pearl Harbor was devastating. It sank or damaged 21 ships of the U.S. Pacific fleet. Two days later, the United States declared war on Japan, and entered the World War Two. The terms of the Agreement between Germany and Japan said that Germany had to come to Japan's aid if they were attacked. So Hitler, who had grown frustrated with the American navy's attacks on German submarines, more than willingly declared war on the United States.
