Is Osama Proud of the Underpants Bomber?

Stephen Walt ponders whether jihadist fanatics are happy that their latest hero has become famous for his underpants: "having an enemy known as the 'underwear bomber' is a pretty good propaganda coup... for our side." (Anybody delusional enough to believe that there's no such thing as bad publicity should just ask Tiger Woods.) And is it just me or does "swaggering sheep" sound like maybe Walt's next book title?
