I would never try a KJF in Revised. Japan’s navy is just too big.
If KJF strategy is used, Japan can see it coming a mile away, and it switches to infantry/artillery/fighter production instead of infantry/tanks.
If the US attacks early, the US has to overcome 2 battleships, 2 carriers, 5 transports, 7 fighters, and 1 bomber (possibly a destroyer too). The ONLY thing Japan has to worry about is the location of the US transport. Until the transport starts threatening (which won’t be for a couple of turns at least), Japan can focus on Asia.
if the US attacks late, the US has to overcome 2 battleships, 2 carriers, 5-6 transports, 1-2 destroyers, 1-4 subs, 10-12 fighters, and 1 bomber. And this assumes most of the US is directed at Japan. If the US even tries to divert to Africa, Japan will be just about impossible to take down.
