When doing a J1 attack I also sink the Hawaiian fleet. I hit the fleet with a couple dd, sub and 4 planes (2 ftrs/2tacs). I then NCM 2 carriers, cruiser and bb to Wake to pick up my surviving air units. Make sure a dd survives the Haw battle to block out the US ships from hitting your fleet at Wake (leave a few ftrs on Japan in case you need to NCM some air in to replace losses). US can try an ill advised air sweep on your Wake fleet, but if you want to play it safe take Wake Isl too. This will give your air units a place to land so your carriers and BB can soak up the first three hits.
I really like this (especially with balance mode because Wake denies USA an NO), and I would also add a bomber that lands on Marshall Islands. The problem is all those planes are not in Kwangsi so you lose the threat of pounding an airstrike on Szechwan or Burma, and you might even have a hard time at Yunnan. You do set the USA way back but you lose initiative on the mainland.
You really need 1 of those bombers against china and the other 1 against the UK BB that you can basicaly kill for free. I just hate leaving a good old BB alive when i can kill it easy it will only help against italy and the more freedom the germans get the more US resources have to go that way.
Another nice way if you J1 is to attack the destroyer + transport of australia with your own destroyer from the carolines, its a crapshoot but a decent chance you win and that will set australia back a lot, and if you dont win well 2 bad that destroyer is nice but it wont make a huge difference for you.
