I never read Evola per se, but I got a strong impression that it's mystical literature in the context of fascist Italy. The people who mention him skimmed through the books for 2 weeks and then LARP as in-the-know.
Anything mystical and esoterical that's discussed on the Internet is utterly clownish; I had my share of that and I'd rather not.
If you want something Axis-style,
Oswald Spengler is a mogger and he's interesting to read. That's the type of man that can take on on the world. Evolians would badly fail to develop weapons and lose to Ethiopia (true story).
