rest of europe will follow eventually if russia is allowed to take ukraine. East side first and rest later after that is allowed to fall too, since why bother with those countries either if ukraine doesnt matter now. after the current war russia will likely spend most of their national capacity on building up the army and equipment. china and russia will likely co-operate enough that china will start the war for taiwan at the same time russia attempts something so that nato resources are needed at multiple places. Maybe north korea will try to attack south too.
