Nietzsche is one of the least popular or influential philosophers in post war Germany. You can say it is for the same reasons that Dix finally abandoned him.

I don't think he is very deep. He is popular now among the alt-right because he thought Christianity was perverted because it glorified the weak instead of the strong.

Hegseth though is hiding on a military base instead of being at the front, so I guess he is weak ...

No one reads "Also sprach Zarathustra" in Germany. It is only famous because of Richard Staruss' symphonic poem, which ties into the point that others made: Nietzsche had various influences, but should not be used for policy decisions. Which is probably the reason this Dix article was published during the first Trump years.
