USA is never a powerhouse. Maybe round 10.
UK is better off investing in India.
Taking out Russia is generally the way to go. If you do go for France. Get AH going to paris with its two closest starting stacks, go through the Italy units. Buy all fighters with Germany. G5 Paris. AH can take a territory for you to allow you to stack up next to paris with all your planes. Then you attack round 5 paris. Send AH in first to suicide. Germany follows it up. The end.
Yeah Russia is a pain in the butt for awhile, but you have to take out a country before round 6 or you lose.
USA is not even in this game, lalalalalala dont know what you guys are talking about. The piece of crap country does nothing for the first 6 rounds.
