I understand your logic guys, and this is possibly one way of making it in the game, yes.
However, I think historical RESULT shouldn't be the goal of the game, or it won't be a game at all. Since Germany would have to lose every game, allies would land in normandy each game etc.
Yeah, no player would do this mistake. That's a big challenge for Germany to try to achieve historical result, not for France to try and make together with Germany some historical dance in order to lose.
If you really want to play with this historical result, you can always start another scenario, in another year, say 1941, no need to make the player to repeat something which could very likely have gone a different road.
However, when I start in 1939 as France (allies) I probably want to experience this early fight as France in a completely different way, and, well, I can't, 'cause France was artificially made too weak, and some people say it should be even weaker to surrender in 4 turns.
