A plot to install a descendant of the German royal family as head of state. Secret outreach to Russian officials for help overthrowing the government in Berlin. Efforts to stockpile weapons and hold firearms trainings. A scheme, influenced by QAnon theories, to incite a civil war to bring so-called “Deep State” elites to justice. On its face, it all sounds like a delusional fever dream melding old and imported conspiracies and the violent fantasies of online extremist groups.
