I think the author is exactly right in his conclusion.
“No, they do not believe in democracy or oligarchy. They believe in nothing. Nothing is true to them, unless it is useful. Nothing is useful, unless it makes them powerful. History and law and logic and the Constitution and morality have one lesson for them: Might makes right. Whatever is strong is true, legal, constitutional, and right.
Ultimately, Rothkopf and his party are practicing Nietzcheans and Machiavellians—not in the philosophical sense, but in the colloquial sense. Power has consumed them.
Their faith is nihilism—and only nihilism can defeat them. To pretend that they believe in anything, even to offer contrary arguments, is simply to play their game.”
He’s right until you get to the last sentence. If everybody on both sides becomes a nihilist it will be hard to get back to anything good.
