Military planners had figured on a sabotage raid as an opening gambit in any Pacific conflict and planned accordingly.
They also didn't believe the Japanese had the range to attack the Hawaiian Islands with any significant fleet.
At this time aircraft from carriers were still something of a unknown quantity. Certainly , airborne attacks aginst ships had been highly successful so far in the war , notably in the crippiling of the Bismarck and the daring night raid by the RAF on Taranto to cripple the Italian Med Fleet (Don't laugh, the Italian Navy was nothing to sneeze at, fast, well armed, and out numbering the Royal Navy Med Squadron at about two to one early in the War), an attack the Japanese basically re-created for the Pearl Operation.
There's actually no evidence that the Japanese studied the Taranto raid at all, and Pearl Harbor was actually planned before Taranto (so more credit to the Japanese planners is due for planning a smart attack).
A great deal of credit goe to luck for the Japanese Task Force had in weather, avoiding American patrols, and merchant traffic. Only a day to so's notice for the Us Pac Fleet, and the whole complexion of the beginnig of the War changes. as it was , the US got an object lesson in the power of carrier based aircraft, a lesson we were only to ready to repay in kind at Coral Sea and Midway.
True. Midway was the turning point of the war. Of course, even then we were working the bugs out of our war machine, since many of our bombers (torpedo especially) were lost in that battle. Of the 18 Avenger crew members, only 2 survived the battle.
All in all, it showed a definite lack of communication between Washington and ONI (not sure what its real name was) and the PacFltInt. Washington had suspicions of an impending attack, but didn't warn Pearl Harbor as to what kind of attack to expect. The most logical to the commanders there was sabotage, so that was what they planned for.
