Pakistan constitutes one of the most important and difficult challenges facing U.S. foreign policy.
What is at stake is considerable by any measure. Pakistan is the world's second-most populous Muslim-majority country, with nearly 170 million people. It shares borders with Afghanistan, where U.S. and allied forces are struggling to promote stability amid a continuing insurgency, and India, with which it has fought a series of conflicts. Pakistan's nuclear arsenal and history of abetting proliferation put it in a position to dilute global efforts to stem the spread of nuclear materials and weapons. And it is host to local extremist groups, the Taliban, and global terrorist organizations, most notably al-Qaeda.
The relationship between the United States and Pakistan has long been characterized by cooperation and recrimination alike. Pakistan is a strategic friend of the United States, but one that often appears unable or unwilling to address a number of vexing security concerns. Political disarray has further hampered Islamabad's capacity for strong and united action. The result in Washington is often frustration mixed with uncertainty about what to do about it.
