I strongly recommend reading Dugin's "The Basics of Geopolitics" (1997). Not because it's a good book, but because it had actually influence a lot of people.
Reading Dugin is a bit like reading Marx/Engels or Hitler: on every single page I was exclaiming "oh no, for fuck's sake, you can't be basing this whole argument on this silly fallacy!!!" -- and then they're still doing it throughout the whole book 🤦♂️
