If the IJN had managed to get enough ships (and troops, preferably marines) to land to cause at least enough damage to the supply, cargo, storage and repair facilities at and around Pearl. My estimate on the attack/raid would be approx. 5,000 marines landed at or near the main channel. They would have been assigned targets for demolition and they would probably be told that they are considered expendable.
The fundamental flaw is, IJN never imagined anything more than an attack to sink the BBs. They thought the war would be short, so destroying facilities, let alone landing SNLF, was ASB as far as they were concerned.
That said, if USN counterattacks, what with? The BBs are sunk, & Kimmel has only 2 CVs against 6.


His aviators are drastically disadvantaged against IJN's, who all have combat experience. Think Midway, with Kimmel as Nagumo.

may include the unfortunate problem of Douglas MacArthur in the European theater
I find that extremely unlikely. With no "Plan South", & thus little likelihood of Japan even attacking the U.S. at all, MacArthur would be put back on active duty & moved from "Siberia" over FDR's dead body.

butterflies required for that to be the case are pretty profound in terms of the overall war
A profound understatement.

Fewer CVs, probably, but more transports & LCs, so good chance for Neptune going off in '43. Maybe earlier, with more VLRs in Coastal Command.

War ending by Xmas '43, with the Sovs not even at their prewar borders? No use of the Bomb?

(Leading to massive nuclear exchanges over Cuba?




) No Sov-occupied Eastern Europe?


No Korean War.

No Vietnam War.

(No "MASH".

No "Trapper John, MD".

No "Magnum, PI"?

No "Tour of Duty".

Oliver Stone never becomes famous.

No "JFK".
