Restitution Round-Robin

Hot news from Sofia, that's in Bulgaria,  where officials are demanding that Greece return nine silver plates, dating back to the 12th century, illegally dug up and smuggled out of the country.(Here's the story, from Sofia News Service, no kidding.) This entire enterprise begins to make the mind spin. Greece wants things back from England; Italy wants Greek items back from California; Bulgaria wants things from Greece, Italy offers to return things to Libya (I'm not even sure if they asked). and Egypt wants things from throughout the Western world. Without diminishing the concerns over looting in Bulgaria, a new and rather virgin hot spot for thieves, at some point one does begin to wonder: where does all this end?
