Maybe if the majority of Europe hadn't acted like little children following WWI and decided to ignore the USA's advice to not severely punish Germany, but instead exact sheer revenge on it, the war wouldn't have even happened!
Maybe if Britan and France hadn't been run by similar pricks who were looking to appease Hitler than do anything to keep him from expanding, Hitler wouldn't have been as powerful and emboldened as he had been!
Hey, it wasn't all Europe. The United State's fundamental lack of understanding regarding European power-politics was bound to cause disaster. Sure, the fact that Western Europe was quick to lay the blame on Germany did contribute greatly [i'd like to see you disagree if you had lived through the period], but I don't remember you guys making protest to Germany being left out of post-war negotiations.
Getting back to the war itself, if anyone should be credited with France making it out in one piece, it should be German leadership, they did a hell of a lot more to win the war than anyone else did.

It's also worth noting that WWII was an inevitable, it was WWI that was the pointless war created by a chain of events linked by freak chance, and a good, heaping portion of arrogance and stupidity by Europe's leaders at the time.
