The war of words between the United States and Pakistan in recent weeks has put in stark relief the two core strategic conundrums Washington has vis-à-vis Islamabad, as well as the integral role India plays in both of them. The first is to encourage a more constructive Pakistani approach in Afghanistan, which Islamabad regards as a theater for its endemic rivalry with New Delhi. The second is to steer a nuclear-armed but deeply dysfunctional Pakistan away from failed state status, a harrowing prospect that many believe is all too plausible unless Islamabad is convinced that its prospering neighbor to the East actually represents an economic opportunity rather than an existential threat.
