Sunni's making a move. Very interesting.
I think there is a connection between the SUnnis making a move and the announcement last week or so that the US troops would not be needed after the end of the year. I do not remember which Iraqi official said it, but I wonder if the plan was to get this over with now by the Iraqis by cleaning up their own house in their own way.
That would be consistent with the US needing its troops freed up in the event of an escalation of the war to include Syria.
