Currently playing as Germany

[cdiplayer]

So I was playing as Germany and everything was going well, I annexed Austria, Switzerland, Kaliningrad and liberated Belarus. Then I decided to attack France and suddenly everything went to hell in a hand basket. Now I guess all of Europe is fighting me and I can't seem to get anywhere. Any ideas on how I can win this war?

When all else fails I used a scorched earth policy. Take their major industrial/military hexes long enough to scrap the buildings then let them take it back. Rinse and repeat til they are too weak to continue fighting.
