That makes no sense. Politics is the local town alderman proposing the opening of a dog pound. Clausewitz's quote is true and has you beat.Politics is also the continuation of war by other means. - Live Canadian dude
The problem with Germany in WW2 was that its greatest military minds were greatly flawed. Around the mid to late 19th century the Kriegsacademie and General Staff stopped teaching and focusing on politics and grand strategy, and things like economics, industry, etc., really only focused on strategy, operations, and tactics. By the point of the creation of the Wehrmacht after Hitler's rise to power they'd basically stopped learning and being interested in anything besides tactics and operations. For them, wars were won by tactical and operational victories that crushed the enemy's armed forces, and thus made them unable to continue resistance, forcing them to sue for peace. And it worked early on, so that reinforced to them that they were right, in Poland, France and the Low Countries, Yugoslavia, and Greece. But failed against Great Britain, and then again even worse against the Soviet Union. Even then, their solution was still to win wars by winning battles, to crush enemy armies using maneuver warfare, forcing enemy politicians to sue for peace.
Hitler was a politician, who dabbled in military studies a bit. He was a keen reader, was obsessed with Frederick the Great, and considering his utter lack of experience and formal education was actually not horrible (though completely irrational, especially as the years went on). His greatest problem, micromanaging the war from a position of influence, was not unique, it was shared by numerous national political leader in WW2, Churchill, Mussolini, all Stalin did the same things Hitler did, and it was only really FDR and Hirohito (who was largely a puppet) who didn't interfere much at all and try to play field marshal. But throughout the war, Hitler was surrounded by generals who were only focused on their own theater and their own slice of the operational scheme, who seemed like they would never take into account the larger picture. It wasn't that Hitler was a genius, far from it, but he should not have been the lone individual concerned with the topics he was. His problem was that the general staff at that time sucked. Hitler should not have been the only one bringing up things like working to keep alliances with other Axis nations intact, as an influence on strategy and operational planning (need for a big offensive in summer '43). Or need for food for the German people (goal for taking and holding Ukraine in Barbarossa). Or independence for oil (taking and holding the Caucasus was also supposed to be a major goal for Barbarossa).
There were only a few German generals who also thought big picture, and AFAIK all of them are considered Hitler toadies. And they were, but they were also the few who looked a the big picture.
