I don't think that Osama bin Laden being dead or alive makes much difference at this point. To kill or capture him would simply be symbolic at this point. He planted the seed of world wide terrorism and it has spread to the point that even he couldn't control it.
He has served his purpose. It would be great if he were dead though.
American intelligence shows that bin Ladin recieved the treatment he needed to keep him alive. When the article says that bin Ladin's death would come as a blow to neo-conservatives is about the dumbest thing I've read in quite a while. How great would it be for the White House to pull a body up on stage and say "look at the great thing we've done!" It would be the biggest public relations event of this presidency.
