Hello.
I'm going to ask you to put aside your opinions on whether it could or would have failed, but I'm asking you forum goers to invent a PoD or several to give the Germans a way to defeat the Allies on the beaches or further inland in France. What would the effects be if the allies were driven back, or if large amounts of men and material (like a Dunkirk gone even worse) were captured or killed? Would, this coupled with an earlier Axis victory in Russia or even a strong defence in 1943-1944 on the Eastern Front, give Germany some space to breath and survive?
Thanks for reading.
