Russia invades Ukraine: now what?

On Feb 24, the day Russia invaded Ukraine, we held an on-the-record discussion, Russia-Ukraine-Europe: What Now?, via Zoom with two experts:
Prof Marie Mendras, Russian specialist from Sciences Po, Paris and Prof Emeritus Douglas Webber, Political scientist & Europe specialist from INSEAD.
Prof Mendras opined that Russian President Vladimir Putin’s shocking and unanticipated move into Ukraine was evidence of continued mental and physical deterioration.
Prof Webber said the invasion would have a tremendous and rejuvenating effect on the EU and NATO, and was concerned that potential Russian aggression into the Baltic states could be a defining challenge to NATO.
