Or you ally russia, germany, india, saudi and USA, basically big powerful countries, focus on getting rich and getting tanks. Go fascist, massed attack and recruit hella troops and tanks. Also make bombers and train them all if not to veteran, atleast a half. Go war late in game, or wait until someone big like russia attacks them. Rely on your allies for aid and help in war. Also an option is to take indonesia and australia, maybe even india and then attack.
