Not so true, the new German Stormtrooper tactics and the 1 million men freed up from the east probably would have broke the French without the new US troops arriving.
1918 is sometimes described as a race between the redeploying german forces and the arriving US forces...
[Note: The Stormtrooper inflitration tactics combined with armor and air are the origins of the WWII Blitzkrieg tactics.]
So you’re saying Germany could have taken France. Even if you’re right, that wouldn’t have brought them anywhere near taking England. Hitler didn’t even try that decades later with a brand new non-exhausted military.
So it still would have meant stalemate, don’t you think?
