I'd distinguish between the paraphernalia and the core ideology. The question is whether Nazi ideology itself was an artistic masterpiece. I think not partly because it was unoriginal. Modernity is supposed to be creative and progressive, but Nazis worshipped a dictator in the same way that ancient societies worshipped their kings and emperors.

I'd say nature's sublime rather than merely beautiful. Beauty is parochial whereas nature at large is thoroughly inhuman. How on earth could a black hole be "beautiful"? Doesn't that drain the word of any meaning?
