Poll question: What's a good benchmark that indicates progress in the Green Zone?

If we achieve Glorious Victory, the (current) mission will be complete and our troops can come home from Iraq. At the moment, we have no measurements to accurately tell us when we are Victorious.

Having experienced incoming on a regular basis during my two tours in Vietnam, I can attest it ain't fun. (One of the things I like about Boston is we haven't had any rocket or mortar attacks in the 30+ years I've been living heah.)

For purposes of this poll, I would like to keep this proposed benchmark tight and focused on something simple.
