Below is an excerpt from a recent interview with Snyder which is a taste of his work and the theoretical perspectives he develops. Because of their depth and wide-ranging relevance, I encourage reading the two reviews:
"What would you say were the basic principles of Hitler’s worldview, and what did that mean for how he viewed the idea of nation-states, or ethics, and other universalist principles we assume as given?
Delman: And that’s a good world to Hitler?
Snyder: Yeah, that’s the only good. It’s a very dark, empty universe. I mean, that’s how Hitler describes it to himself. There are really no values in the world except for the stark reality that we are born in order to take things from other people. And so Hitler sees the only good thing as removing the Jews who pervert, as he says it, human nature and physical nature.
Snyder: Yeah, so unnatur is actually a term that Hitler uses, and I think it’s a really telling term. I think it gets to the heart of the matter. When we think of anti-Semitism, we start from the ground up, right? We think about everyday prejudice. We think about discrimination. We think about the separation of Jews from other people.
Here is another review which encapsulates Snyder's position; "He does not see the Holocaust as a “war against the Jews”—as the historian Lucy Dawidowicz called it—for which Hitler was prepared to sacrifice ordinary military strategy, but as an extreme example of Hitler’s wide-ranging racial obsessions":
