Some random thoughts.
Individual Russian units are fierce fighters. There is no quit in them. But they are often poorly lead and almost always badly supplied. Think of all those Lend Lease Studebaker trucks we gave them to mechanize their army.
My sense of it is that old uncle Adolf was more gambler than strategist. With training, advice, and experience he became a pretty good staff officer but first and foremost he was a politician. And like Napoleon he felt he needed military victories to maintain himself in power. You can talk 'Mien Kampf' all you want but I would say that he only had a hazy idea of his ultimate goals; but took advantage of any opportunity he saw when he saw it.
Field Marshal Manstein is one of the top five commanders of that conflict regardless of side. Thank the Gods that Hitler could not abide a rival.
Clausewitz's dictum about "no plan surviving contact with the enemy" and Wellington's comment about the "fog of war" rule here. For that matter in contemporary times; the 'W' people not seeing the evidence before their eyes regarding 911 is another good example of this. There are good reasons why it is referred too as 'The Art of War' rather than the science of war.
See Stalin's comment to Churchill and Harriman about oil and internal combustion engines. Or, for that matter, Churchill's acquisition of the oil fields of Iran to ensure that the Royal Navy & especially the Queen Elizabeth class battleships had a secure source of fuel. Hence British Petroleum. The Crowns controlling interest in Bushmills whiskey is another good example. Grin!
There is now hard evidence that Japanese Imperial Army planners told the cabinet that there was only a 9% chance of outright victory against the western powers and this was in the summer of 1941. My sense of it is that they choose to follow their code of honor rather than seek a meaningful accommodation with the west. To quote the old Klingon proverb: Today IS a Good Day to Die!
