Will someone just kill him already?

Muqtada Al Sadr causes problems in Iraq yet again. Can the US just assassinate his ass please? The man had it coming for years now and i am sure he is not going to be sorely missed by anyone other his crazy followers, who will resume being smelly stupid unemployed men the moment he is gone. I just don't get it. Innocent people die there every day, why not him? It's just not fair!
