Increasing militant activity in western Pakistan poses three key national security threats: an increased potential for major attacks against the United States itself; a growing threat to Pakistani stability; and a hindrance of U.S. efforts to stabilize Afghanistan. This report addresses this issue at length. It also describes the recent upsurge of militant activity on the Pakistani side of the Pakistan-Afghanistan border, as well as the general political climates of Pakistan and Afghanistan and their relationships with the United States.

Pakistan - a key U.S. ally in global efforts to combat Islamist militancy - is in urgent need of an estimated $4 billion in capital to avoid defaulting on its sovereign debt. The Pakistani government is seeking short-term financial assistance from a number of sources, including the International Monetary Fund (IMF), China, and an informal group of nations (including the United States) known as the "Friends of Pakistan." The current crisis has placed some strain on U.S.-Pakistan relations.
