OK, different topic.
I have before criticized German generals like Halder or even the famous Rommel for not understanding strategic goals. Like, Halder overriding Hitler's orders and going for a random line through Russia (that included going after Moscow instead of the Caucasus oil fields) or Rommel started a push towards the Suez Canal even though the Brits had closed it on their own (to not risk the raids of the Italian Navy) and his only actual strategic goal was only to keep Italy from dropping out of the war.
Some months ago I was listening to an actual historian (dumbly I can't remember who), who said something along the lines that Germany didn't have a strategic thinking school in WW2, they only had operational-level thinking. Like, at best their planning is at the level of
1. Win this OPERATION.
2. ???
3. Miracle happens here.
4. WIN!!!
Not in those exact word, but no planning actually got above the level of operational.
And everything clicked in for me. They had moved from WW1 tactical thinking (which already explains WW1), to interwar operational thinking. Literally nobody (in the military) than Hitler actually planned around strategic objectives, nor around achieving them.
Don't get me wrong, I'm not saying that Hitler was good. He was a psychopath and one of the most evil people ever. I'm just saying that his military was even worse at understanding what is the POINT of thrusting in a particular direction, they only ever learned HOW to do it.
