Probably did not notify Malki for fear his people would warn the militia of the impending attack and whomever was the target for the raid would dissappear.
Sadr isn't the target me thinks. We are just sending a message. But there needs to come a time when we take him out. Yes it will cause a big uprising, but we will just need to kill those that get out of line until it dies over. It seems that everyone but our Military and GWB have gotten the message that the only think these people understand is brute force. After Nov 7th, providing repubs hold the House, it's time to kick some.GWB can't leave this for the next President.
