As U.S. Troops were reportedly nearing the city's outskirts, Muqtada al-Sadr was preparing several squads for guardianship of the ancient relics of Iraqi history. He sent troops to guard the museum that contained some of the earliest relics or human activity on the face of the planet. He was there to prevent looting. U.S. troops were totally indifferent to the building and its contents. Was it worth it to piss him off? He wasn't there to defend Saddam. He was perceived as a threat and fought, without question. Now the U.S. has another new enemy.
