I wonder if a 'Russia 1917' scenario is possible... had the war take a nasty turn for Saddam, could inner troubles start, perhaps with the proposed iranian influences AND kurds rising up, or at least factionalism in generals and all.. and Baghdad falls to troubles and out of Sadam's hand, if not by iranian hands.
Maybe if by a random accident, a very lucky bombing.. or fragging.. Saddam and his inner circle are killed...
