President Obama is right to feel triumph at the death of bin Laden, and the American military and intelligence should feel pride at a job well done. But let’s hope that the White House and the diplomats also learn another lesson: Unilateralism works. The Pakistanis were only informed after the fact because, let’s face it, Pakistan is more adversary than ally. We didn’t run our plans by Moscow or Beijing, let alone Brazil, Gabon, Germany, or Nigeria, or other members of the Security Council. Multilateralism might bring some artificial sense of legitimacy and might give diplomats something to do, but there’s no multilateral substitute for a mission accomplished.
