First, the battle of Britain is nothing like Pearl Harbor. BoB was air versus air, or air versus ground. Not air versus sea. Second, yes, I've heard of Taranto. However, it was done with such a low key scale that it was relatively ignored. And another big difference is that the Italian fleet was isolated within 3,000 miles. It would have been easy just to launch from Africa, Spain, Egypt, the Middle East, or almost anywhere in Europe and make that raid. Japan was considerably a great distance away from Pearl Harbor. That's what I refer to.
