Nevertheless, every one of these dead noncombatants represents an alienated family, a new desire for revenge, and more recruits for a militant movement that has grown exponentially even as drone strikes have increased.

Second, public outrage at the strikes is hardly limited to the region in which they take place — areas of northwestern Pakistan where ethnic Pashtuns predominate. Rather, the strikes are now exciting visceral opposition across a broad spectrum of Pakistani opinion in Punjab and Sindh, the nation’s two most populous provinces. Covered extensively by the news media, drone attacks are popularly believed to have caused even more civilian casualties than is actually the case. The persistence of these attacks on Pakistani territory offends people’s deepest sensibilities, alienates them from their government, and contributes to Pakistan’s instability.
