"War For Eternity"
goes into some depth about Olavo, his role in Brazil, his exile in America and his work with Steve Bannon -- and his amusing rivalry with the big homie Alexandr Dugin. If this stuff interests you, very much worth picking up. A bit muddled, too. It's the work of an ethnomusicologist from Colorado (who swears he's not a spy, bro!) who did a book on "Nordic Radical Nationalism" and their music scene, so he already had inroads and connections to the globalized whateverology. Fascist Internationale, as some of y'all call it.
Also, he loves ice cream.
