Stephen Miller is clearly Himmler. They even have a certain physical weirdness in common. The Goebbels part of the operation has seen some substantial improvement; I think they have learned that it works better if you don’t have one visible person who’s in charge of the propaganda, but just a shadowy network that’s smuggling various things that are “what everyone believes” into the discourse. I don’t think there is really an equivalent of Goebbels in the modern setup.
