Ray, I've got something over 200 books on the shelves regarding WWII; it is one of my interests as a result of the shadow the depression and (the resulting) WWII cast.ray nelson wrote:The Axis had no idea of the capabilities of the USA before the war. B17 production stopped in 1945 with a total of around 12,700 planes. The war effort consumed almost all manufacturing during the war years and to quote "Bunky" Knudsen; an automotive industry executive "We won because we smothered the enemy in an avalanche of production, the like of which he had never seen, nor dreamed possible".[...]
Of all the books, "The Wages of Destruction: The Making and Breaking of the Nazi Economy" (Adam Tooze) pretty much makes the case best; the Nazis had one possible chance of winning: England had to offer negotiations prior to the Summer of '41.
After that, there was no possibility of a Nazi win; all-out war is an economic contest. Germany's econ had not anywhere close the resources to recover, let alone win.
