We're not there yet, but we're
getting closer, with tens of dead and hundreds of wounded since Monday (and one dead US soldier, making me wonder if the 1'000 awful milestone won't be hit before next week).
This time, there's no major holy shrine the troopers should take care not to damage. But contrary to Najaf's 500.000 people, most of who supported only softly Sadr if not openly disliked him, you get a 2 mio urban area where people are fiercely loyal.
Oh, and notice that they now openly claim "thousands of deads in Najaf". Saddam must be ironically smiling in his cell, seeing how "well" the US Army deals with restless Shia.
