Larison challenges this line of reasoning:

[T]he more that Americans come to believe that killing individual leaders is a ready-made solution to policy problems, the easier it will be to sell supposedly low-risk, promiscuous interventionism facilitated by missile strikes or special forces. It also helps to keep people from thinking very much about any of the other things that stoke jihadism and insurgency, and it encourages the false comfort that we just need to kill enough of the right people to prevail.

Sure. But we are not supposed to be glad that this monster is dead? Please.
