I'm going to reply apolitically to the political.
Wars... are... always... about... resources. Period.
Politics, religion, etc are mere "excuses."
As to Rudel. I've only vaguely been aware of him being a stuka ace and nazi. I did read the "book" - thx fester.
I'll give him his single-minded dedication. I do wonder how he may have turned out if he served on the West Front, as opposed to the Eastern, which in his eyes seemed to be the enemy moreso than the jews per se - the "facist" vs "commies" aspect of the nazi party. But then, since I haven't delved too much into him, or any aces for that matter, so if he was vocally anti-semite I'd look at him lesser than I already do. That's the *man.*
As an insane person and pilot, no one can dispute his single-minded dedication to flying and shooting up @#!%
