The world has been transfixed by Ukraine’s fight for survival. As the war drags on, we’d better start considering what will become of Russia, as well.

President Vladimir Putin’s nation has now been subjected to an isolation more sudden and total than that experienced by any major power in recent history. What that leads to may not be pretty.

Since late February, Russia has been hit with punishing economic, trade and financial sanctions. It is careering toward a debt default, as a rapid technological decoupling is also under way. Foreign firms are fleeing the country, while Russian teams are excluded from international competitions in soccer and other sports. Even the International Cat Federation has barred Russian felines from its events.
