Marc Lynch takes Iraq's temperature:
The situation is extremely murky, and it's hard to really know anything with confidence. What I've been seeing in the Iraqi and Arab media, and hearing from the people I've spoken with, is a wide range of competing interpretations and arguments over everything from the identity of the attackers (al-Qaeda? rival Awakenings groups? Shi'a militias looking to stir things up?) to the intentions of the Iraqi government (eliminate the Awakenings? weed out the 'bad elements' within them? force the U.S. to take sides, and test the U.S. implementation of the SOFA?). The high level of uncertainty and confusion is itself a significant point -- the impact of fear and uncertainty on strategic calculations should never be underestimated.
