Now, if you emptied the harbor of capital ships for a strike force the
Japanese spies would have relayed the information back and the jap fleet
may have turned back. Or set up for attack.

Umm, then how come the Japanese spies didn't tell the fleet that the
carriers were gone? As far as I know, right up to when the Japanese were
over Oahu they thought the carriers were there.
