Der Spiegel (Melanie Amann, Jörg Diehl, Martin Knobbe and Andreas Ulrich) on AfD and the Federal Office for the Protection of the Constitution (BfV):

'In the future, the AfD's leaders will have a harder time dismissing Höcke as an insignificant regional player. From now on, the BfV will register how the party's high functionaries react to his outbursts, with the report citing Höcke's call last September to join demonstrations in the eastern German city of Chemnitz, which was the site of a weekend of ugly race riots. Intelligence officials said the city became host to an "extremist-friendly mix" of normal citizens, neo-Nazis and hooligans.

Despite the report's findings, the BfV agency's interventions against the AfD likely won't be terribly disruptive. While it's true that intelligence officials could use covert surveillance to monitor "The Wing" and the "Junge Alternative" more closely, the methods used would have to be proportionate. That means eavesdropping on phone calls is pretty much out of the question. To do that, the "G10 Commission" in the Bundestag would have to get involved, but that step is generally only taken against Islamist terror suspects or violent right-wing or left-wing extremists. It's also unlikely that the BfV would be permitted to use informants, according to officials. At most, the agency could install observation teams and save person-specific information in the data network shared by Germany's federal and state-level intelligence services.'

So the Federal Office for the Protection of the Constitution can't do much at the moment, and the hope apparently is that AfD will slowly but steadily peter out.

But extreme-right violence has been a reality for years, yes, it cannot be compared to the violence during the Republic of Weimar, but that's hardly comforting.

What did Heidegger say again in an interview with Der Spiegel in 1966 again? "Only a God can save us."
