The latter "denazification" is laughable considering the previous atrocities by Chechen brigade supporting Putin right now in Ukraine and "nazi's" like the Asimov Battalion also exist within the Eastern Ukraine separatists. Let's be clear, Putin was never really concerned about "nazis" but the Asimov Battalion is a useful rhetorical tool for his propaganda machine.
Putin cares about Nazis like the East Germans cared about Nazis when they built the Berlin Wall (officially the AntiFascist Protection Rampart).
