I’m not a big Clancy fan, I will read this one.
The book and the movie are quite different on this point. This has nothing to do with the book or the opera. The music in the opera is used as the background music for killing off neo-Nazi deep state schemers. In the book the terror attack with a nuclear weapon is carried out by Muslims, with German Marxist accomplices. In the movie, white neo-Nazis. In the book the German Marxists hold the Muslims (and their Amerindian accomplices) in contempt, but work with them out of convenience.
