According to this article in Salon, here’s what the “peace deal” in Najaf looks like:
On Friday morning, the number of armed men on the streets of Najaf did not seem to have diminished, and in places it seemed to have increased. And as of late Friday afternoon, Mahdi army volunteers were still streaming into Najaf, responding to Muqtada’s call for assistance, some coming from other countries. The numbers of militiamen were growing significantly. Pickup trucks full of men with heavy weapons were parked on the street leading to the medina, or old town. Many of the fighters were from out of town. The trucks had been quickly painted over, and the faint image of the blue Iraqi police lettering was still visible.
With the pressure from the United States abated, the Mahdi fighters spent Friday acting as if they had just won a great victory.
Sounds like Fallujah déjà vu.
