Go back and re-read Commissar's post.
Even if Lt. Tyler is given full ASB knowledge of the next 5 years... there is not a damned thing he can do about it. By the time he can find a phone, reach anyone who will answer at Wheeler... it will be too late. It would take hours, in reality, to get those aircraft fueled, boresight the guns, sober up the pilots... by the time the Japanese show up on radar, about 50-odd minutes before the first bombs fall, it's just too late. Even with good communications, only a handful of fighters were in condition to actually fight at 0755 on Sunday morning. And there are no such communications.
Readiness is a thing which cannot be improvised after the fact. By dawn on the 7th, the battle of Pearl Harbor had already been lost. Fuchida merely served formal notice.
