Of course, it is a foregone conclusion that it is a DECISIVE JAPANESE VICTORY.
I take little pleasure in the result because it seems the AI is incapable (or perhaps not programmed) to fight this scenario.
The AI certainly showed tenacity in repeatedly mounting invasion attempts, first at Attu, and then at Kiska, despite huge shipping losses and the loss of so many troops when Transports went down.
However, it showed very little guile, or tactical ability. Guile was limited to occasional feints to and from the island intended for invasion. Tactically, to lead with poorly escorted Transports without even Surface Combat cover or the small Carrier, all of which were available, in attendance was virtually suicidal.
Air attacks against my shipping were rare and restricted to the immediate vicinity of Adak. CAP was provided over Adak but rarely for Task Forces approaching my air cover. Air raids were sporadic and poorly coordinated and it seems the Liberators were hardly used, with Mitchells doing the 'donkey work' and suffering for it.
Once it made landfall, then the AI fought adequately with its ground forces but it left them hopelessly low on supply.
So, overall, I am very disappointed with the AI performance.
