It's nice to see dictators in the dock, even if it is an artificial international tribunal located somewhere like the Hague.  But there are many reasons to be skeptical of proposals to create new, super-national bodies. 

Consider the recent overreach by the Yugoslavian war crimes tribunal.  This court is supposed to try "war criminals" who committed atrocities in the Balkans.  But in December it tried to prosecute a French journalist for reporting on its activities!
