Axel… Pearl can be done without a single FIG if you want to (1 SUB, 1 DST, 1 AC, 1 BOM) with a reasonable chance of success. Add in the Caroline FIG (that can;t reach any land area for attack in J1) and it is pretty much a given against just 3 US units.
Also, the US does not need to “recover” squat after losing Pearl UNLESS they are going KJF. They just lose the navy, build their TRN’s in the Atlantic, sail the Panama DST to the Atlantic, along with ther SZ10 DST, and then link up with UK ships in or near SZ7 and away they go…
Not doing Pearl, Japan settles to SZ61 in J1 and builds their trannies there. If the US comes after Japan with just the Pearl fleet in US1, there is nothign for them to hit in SZ60, and there is no tranny for them to even try to land in Japan. In J2, you smash the fleet in SZ60. If they wait and combine fleets at Pearl in US1, then you build a couple of subs, plus more trannies in J2, place them in SZ60, move your BB and TRN’s from 61 to 60, and very likely move an AC and/or BB from FIC to SZ60. Go ahead US, attack THAT fleet.
I have played a game where the US had MASSIVELY built up in the Pacific. Multiple AC’s, all loaded, multiple BB’s plus a lot of subs and trannies, DST’s, the works. He even had an entire EXTRA wing of FIGs for each AC so that he could “fighter exchange” and double the number of FIGs in a naval battle.
I WON that game, with a Japan fleet still in the water.
