I think it depends on what he wants to accomplish. Georgia was small potatoes. Russia got some territory it could set up as vassal states and purge of non-Russians. With Ukraine it seems the initial plan was to take the whole country. It has a great deal of strategic, economic and cultural value. At this point he might settle for lands taken, NATO recognition of those areas as an independent state or an official part of Russia, and a guarantee that Ukraine would never be admitted to NATO. That’s a hell of a lot to give up for a country we promised to protect.
