I hope this doesn't sound stupid, but what is the Iversonian school? I googled it and didn't get any immediate results.
I've been thinking some more about HistLover's comment about how these events will be remembered and an interesting parallel occurred to me. If OTL's WW2 bears some similarity to the Napoleonic Wars, with France as Germany, TTL's Nazi Germany parallels the earlier conflicts extensively. Let me lay out the similarities (some of which apply to OTL of course)-France suffered humiliating defeats in the Seven Years' and American Revolutionary wars, which then combined with internal economic turmoil. Germany suffered defeat in WW1 and suffered economically from the subsequent Great Depression. France then experienced a revolution and subsequently regained much lost ground (natural frontiers, left bank of the Rhine, etc). Nazis took over Germany, rebuilt its power, and regained/took territory (Rhineland, Austria, etc) Under Napoleon, the French then launched the 1804-5 war against a British-led coalition. With a combination of skillful tactics and luck, he prevailed against Austria, then turned on Prussia with similar results. Finally, he turned east towards Russia, achieved a solid victory and used it as leverage to negotiate the Treaty of Tilsit. The period 1807-12 was the height of his empire. But France could not live with the down but by no means out Russia, and thus Napoleon went east once again. Under Weber, the Germans launched the 1939-40 war against a British-led coalition. With a combination of skillful tactics and luck, he achieved victory against Poland and France. He then turned east towards the USSR, won a solid but by no means decisive victory, and used it to leverage the Treaty of Sofia from the Soviets. The period 1942-195(?) marked the height of Weber's empire. But Germany could not live with the weakened but still formidable Soviet Union, and he therefore moved east again. Here, our chronicle of the Weberian Wars breaks off, but can we use those of Napoleon to fill in the gaps? Undone by a combination of hubris and logistical breakdowns, his Grande Armee melted in the Russian winter like snow in spring. Which is to say, maybe the answer is simply that the Wehrmacht, although it should be able to win with the resources at its disposal, will have been made complacent by its earlier victories and will mess up badly when war is renewed, leading to a similar catastrophic failure.
There is also the issue of leadership. OTL Weber died in 1954 at 62. Stalin died in 1953 when he was, IIRC, in his early 70s. Their deaths, or incapacitating illnesses are another wild card.
I am curious what my fellow readers think of the analogy. Does it provide some insight? Am I seeing patterns that aren't there? Should I just shut up?
