Newsweek has a good piece by 
Christopher Dickey.  It mentions all the conspiracy theories that float around but then mentions another overlooked bump in the road for Iraq.  October in Iraq, the temp is dropping and Ramadan begins the 16th.  
In the immediate future, this Sat. the 
Iraqi National Conference will meet for a three-day event.  How many officials does Iraq have left?
Something to keep an eye on.
