NATO's operation in Libya has rightly been hailed as a model intervention. The alliance responded rapidly to a deteriorating situation that threatened hundreds of thousands of civilians rebelling against an oppressive regime. It succeeded in protecting those civilians and, ultimately, in providing the time and space necessary for local forces to overthrow Muammar al-Qaddafi. And it did so by involving partners in the region and sharing the burden among the alliance's members.
NATO's involvement in Libya demonstrated that the alliance remains an essential source of stability. But to preserve that role, NATO must solidify the political cohesion and shared capabilities that made the operation in Libya possible -- particularly as its leaders prepare for the upcoming NATO summit in Chicago this May.
