If taking out Sadr brought Sistani off the sidelines and into the anti-American Shiite camp, it would not do anything to help achieve the "winning condition" you reference and would likely hinder it immeasurably. We presently have a large majority of the Shiites not actively seeking to undermine our efforts. Want to change that?

Gee, ummmm..... wasn't that the strategy from April - July 2003?
It sure has been paying off.
