The reason the aircraft carriers were not at Pearl is because they were the most important component of 1940s modern warfare. They were made to leave just in time.

That is an overstatement to the max. Very few American admirals knew the strategic and tactical value of their aircraft carriers until they became valuable assets after the attack on Pear Harbor.

Until then, they were considered support vessels for battleship centric fleets.

After British fairey swordfish biplane torpedo bombers sunk the Italian fleet at Taranto Italy in November 1940, the WORLD knew it. The Japanese based their Pearl Harbor attack on it.
