Actually, full up wargames were run in 1926 simulating a full attack on Pearl by the empire of Japan, including carrier based planes.
Describing 1926 operations: "(USN Commodore) Reeves used annual fleet exercises (Fleet Problems) to demonstrate new tactics, such as high-speed long-distance steaming combined with undetected predawn launches and coordinated dive-bomb attacks against targets ashore. Finally, Reeves seized upon opportunities to demonstrate the offensive potential of the carrier. During war games, he foreshadowed the Day of Infamy by launching a dawn attack against Pearl Harbor."

Yes....that's 1926.
Pearl Harbor was VERY MUCH predicted, and practiced.
This naval aviation visionary also accomplished other feats as well:
"In January 1929, the U.S. Navy undertook another exercise known as Fleet Problem Nine. Fleet Problem Nine took place off the coast of Panama. Present for the first time in these fleet problems were two ships of radically new design—the aircraft carriers USS LEXINGTON (CV-2) and USS SARATOGA (CV-3). During the exercise, Vice Admiral William V. Pratt, commanding the attacking force, authorized Rear Admiral Reeves, commanding the SARATOGA and a light cruiser as escort, to execute a high-speed run toward the Panama Canal. "We take off at 3:30 a.m. to bomb the canal," an excited Lieutenant Artie Doyle wrote on the eve of the landmark attack. "They haven't a chance to stop us." Reeves "attacked" the canal with a seventy-plane strike force launched 140 miles from the target.
"The planes struck without warning in an attack deemed so effective by the referees that they ruled the locks at the Pacific end of the canal destroyed.
The SARATOGA's performance changed naval warfare; she had demonstrated that a speedy aircraft carrier could independently attack enemy installations with devastating results. Admiral William V. Pratt, the Black Fleet Commander for this exercise, was so impressed that he moved his flag to the USS SARATOGA for the return trip to the United States. (11)
In his post-exercise critique, Admiral Pratt made the following comment, "Gentlemen, you have witnessed the most brilliantly conceived and most effectively executed naval operation in our history. . . . I believe that when we learn more of the possibilities of the carrier we will come to an acceptance of Admiral Reeves' plan which provides for a very powerful and mobile force . . . the nucleus of which is the carrier." (12)"
Yet compared to Mitchell very few have heard of Admiral Joseph Mason "Bull" Reeves, USN
(1872-1948).
"US Army Snipers...providing surgical strikes since 1776."
