The Pearl Harbor attack was a brilliantly planned and executed air assault, a horror for my brethren sailors of an earlier generation, and a terrible strategic error by the Japanese that poked the hornets nest of U.S. entry into the war. Many Japanese flag officers knew this was a mistake from the beginning. The U.S. "got it back" much earlier than the end of the war at the Battle of Midway, where Admiral Nimitz laid off the island to the northeast (I believe it was) and then caught the Japanese aircraft carriers between launches of flights and basically ended Japanese naval dominance in the Pacific for the duration of the war, despite much bloody resistance at sea and on the islands. At Pearl Harbor itself, the Japanese had an enormous tactical set-back, despite their massive victory, but hitting battleships but no aircraft carriers, which was an intended target. The carriers were all elsewhere at sea or getting refitted in yards on the mainland.
