Who do you all think was to blame for Peral Harbor? I think somebody should have thought about an air attack, from carriers. After what the Brits did to the Italian Navy at Taranto, measures should have been taken to guard against an air attack. Italians used aircraft engine, sound detection, to protect their fleet. So, the Regia Marina (Italian Royal Navy), knew the Brits, in their Bi-Planes were comming. Yet, the raid was still very effective and the Regia Marina was relocated. The US should have had a well trained and staffed, 24 hr radar station, as well as other defences. Also, did it make sence to create such a big target, as 7 battleships in a neat row, in a harbor, with a lot of other tempting targets. Like carriers, cruisers, dry docks, subs, oil storage etc. I know the carriers weren't there, but that was just by luck. Somebody was asleep at the switch.
