I don’t think D Day happens anything like it happened .I don’t necessarily think Normandy would have been in play. Our strategy would have been far different from the get go.
As it was, it took some mistakes by Rommel and Hitler to allow D Day to work. Had they had all those other resources, it just simply could not have happened.
And then who knows what Stalin might have done. He would almost certainly have captured Japan.
If not for Fat Man and Little Boy, most like Japan would have been divided, like Korea and Germany.
