"On Tyranny" by historian Timothy Snyder was published int 2017.
There was also a comparison (by historians) dated prior to the 2016 election marking the very real similarities, but of course, everyone poo-pooed it and here we are.
And there is reporting that 34-felon had a book of Hitler speeches on his bedside table (per his x-wife). I'll need to look up that reporting, but it tracks with his repetitive phrasing. He's playing a part and Hitler wrote his script.
