I'm sure they all look the same to you, but Fallujah is a Sunni stronghold, whereas Al-Sadr is a Shi'ite, from Najaf. Of all the things you can blame Al-Sadr for, Fallujah is not one of them.
My bad.
I;m glad that someone else called him on that.
Sadr is an ass, but he didn't have anything to do with Fallujah.
