You’re discussing Jan 6 as a (non) occurrence of a specific type of coup, a Coup d’etate. That’s not the only type of coup there is. The Coup Project at University of Illinois at Urbana‐Champaign has categorized 12. See for yourself at https://uofi.app.box.com/s/koi8js58bsdz8f2zg778vi0uem4gu69k.

In the meantime, had this “event” succeeded, what would you have called it?
