Here’s Petraeus, as per the BBC:

“The rockets that were launched at the Green Zone yesterday, for example… were Iranian-provided, Iranian-made rockets,” he said, adding that the groups that fired them were funded and trained by the Quds Force. “All of this in complete violation of promises made by President Ahmadinejad and the other most senior Iranian leaders to their Iraqi counterparts.”

Iran is desperate to convince the world that the United States is not winning the battle of Iraq. Nothing would be as helpful as a devastating attack on our citadel in Baghdad. Note that the Quds Force is NOT a proxy; it’s part of the Iranian armed forces.

Note also that their solemn promises to be good were worthless. Somebody might tell the secretary of state and her minions, desperate as they are for some “grand bargain” whose value would be the same as the “deal” with the Iraqis.
