Here comes the problem, I am constatntly running out of supplies with Japan, I always take the majority of China(which may be a mistake as I'm finding out, it takes up too many resources but I want easy access to Siam and sw of there since the USA will constantly concentrate on Germany(at least with supplies), I don't have enough supplies for my ships which leaves them as floating ducks since I attack and then I'm stuck.
Any help or strats would be appreciated. Thank you-
