This is Iraq

The US is conducting a sweep of Diwaniyah, a Shia stronghold south of Baghdad,

Pamphlets dropped by U.S. helicopters warned police, who are suspected of being infiltrated by the militia, to stay off the streets. Any found carrying weapons would be shot.

Doesn't that just say it all?

Are the US forces going to stay there forever, or will they put those same militia infiltrated police back on the streets in a week or two? What is the longterm point of this operation?

Also, notice in this article that the US/Iraqi forces "discovered a factory that produced EFPs" (Not manufactured in Iran,) and that the fatal British attack was not an EFP, but a "new type of bomb," maybe a commercial landmine.

Later: An AP article on the operation in Diwaniyah.
