Our Japan player elected not to use the J1 attack. America came into the war on turn 2 though. That worked out well for Japan overall as he was able to establish himself better in the money islands before having to deal with America.
Germany elected to keep Russia out of the war the maximum 3 turns (Russia declared on his 4th turn). He now regrets that and wants to play Germany again when we play our 2nd game and press Russia sooner.
