What was the outcome of Pearl Harbor?

Answer 1

The basic outcome of the surprise-attack on Pearl Harbor by the Japanese in December of 1941 was to awaken a fighting spirit in the American people. While America had suffered a temporary defeat, with a number of important ships damaged or sunk, the more important result was that American pride and security were violated: Americans now wanted to fight -- and to fight until final victory was achieved.

Answer 2

The U.S. and Britain declared war on Japan on Dec. 8th.
