You have some serious reading to do. Pearl Harbor did not attack Japan. The US Naval Base at Pearl Harbor HI was attacked by the Japanese on Dec 7, 1941. The American ships were tied up at their morring points in the harbor, and there had been no declaration of war. This was an unprovoked attack by Japan on the United States.
