"Yep, I think you make a valid point. Any decent WWII war game should show those results."
I'd like you to expand on that if you care to. While I've read a fair amount of military history, and had an interest and experience with games like Stratego, chess, Risk, and some Milton Bradley, Civil War game (I'm talking about the 1960s), I have never played the sort of game you refer to (maybe tried a hexagonal game one time).
On the face of it, it would seem like a realistic recreation of the situation Kimche describes would not be "game like" because once the Germans attacked Poland they would certainly lose. I suppose, however, they would not attack Poland. But then I can see how they would win either.
