No B.S. is going to remove that; it's said the attack on Pearl Harbour was modelled on Taranto; difference is, chum, that we were already at war, not a sly back-stabbing move like the Japanese made.
The nagging thing here though is the USS Ward actually sank a Japanese Submarine just outside the harbour zone before war was declared and before the attack... Never sat comfortable with that fact, but totally off topic anyway.
In the hours before dawn, U.S. Navy vessels spotted an unidentified submarine periscope near the entrance to Pearl Harbor. It was attacked and reported sunk by the destroyer USS Ward (DD-139) and a patrol plane. At 7:00 a.m., an alert operator of an Army radar station at Opana spotted the approaching first wave of the attack force. The officers to whom those reports were relayed did not consider them significant enough to take action. The report of the submarine sinking was handled routinely, and the radar sighting was passed off as an approaching group of American planes due to arrive that morning.
