The Iraqis themselves in a year or so can declare these abettors as war criminals and ask for the various countries to arrest them and send them to Iraq.

That appears to be the thinking of these that seek to prevent the Iraqis from becoming a civilized place. So long as these terrorists killers, political counterparts (our liberals) continue sounding the clarion call to join the war, it may well take a whole lot longer than a year for the Iraqis to govern.
