This whole thing is a nice, warm piece of red meat for the political wranglers.
Not hard to deduct that al-Maliki created this recent mess by trying to make Iraq a Shiite state.
The Kurds and Sunnis were left out....what's happening now was predictable.
So now Kerry is going to go over there and try to teach al-Maliki how to create a unified government ?
I don't think think so....too late for that.

There was the American War
Then the 1st Civil War
Now it's the 2nd Civil War

This will have to play out and the result will be one of 3 things, just as it was after Saddam's fall.
