That is why I said “might.”
Germany declared war on four nations, each with bigger economies and more population than all of Germany. It never fails to amaze me that they got as far as they did; they took out one, and put another (perhaps two others) on the ropes. I think it is barely possible they might have pulled it off, perhaps in the very unlikely event of support from Japan.
Of course the leaders of Japan were ever more idiotic. They pissed off a country which had individual STATES with more miles of paved roads and rail roads, and more industry than all of Japan...
“Germany declared war on four nations”
The only country Germany declared war on in WWII was the United States.
