I read this last night. I was surprised it was so short. Small and 126 pages but it covers some deep material. It was released in 2017 in response to the former president I assume. He compares him to other events in history. What really struck was his prescience about the Ukraine war. It didn’t predict it but gave the conditions that did. I think he drifted a bit in some sections where he assumed too much of a neophyte reader but anyone would benefit from the book. 21,000 plus 4.5 star reviews
He gives a summary of some his points here.
How Fascism Works: The Politics of Us and Them
I read this last fall. Also recommended.
