The CIA's Silent War in Pakistan

For all the caveats, the hum of the machay will grow louder in Pakistani skies this summer. The arrival of more U.S. troops in Afghanistan will make it all the more important to deprive al-Qaeda and the Taliban of their safe haven in Pakistan. Obama is widely expected to authorize a broadening of the drone attack to include the southwestern Pakistani province of Baluchistan and its capital, Quetta, where the Taliban high command is thought to be hiding.

But in the long term, the Pakistani frontier can be safe only when the tribes are more favorably disposed toward the U.S. and the Pakistani government than toward the militants. The U.S. hopes that can be achieved by supplementing the drones with development aid, much of it earmarked for the tribal areas. But can that money start working its magic before the resentments roused by the drone campaign metastasize into an irreversible jihad? On that question of timing may hinge the success or failure of a modern war fought in an ancient environment.
