Coward or What?

Moqtada al Sadr is pulling either one of the smartest moves while waging this battle, or is an incredible coward. I'll take the latter over the former on this one becuase he is simply hiding out in the Imam Ali Shrine, one of the holiest places in the Musilm world. If the US forces went in there to get them, a significant amount of damage would be done to the shrine, which would cause a much larger uprising than what is currently going on.
