It doesn't necessarily work that way. Killing Al-Sadr would probably lead to a massive revolt against US troops, plus there would be no one else to control the Mahdi Army, at least not immediately. Al-Sadr is actually the reason it's been fairly quiet in Iraq over the past several months because he declared a unilateral cease-fire and most of his followers obeyed.
