This Congressional Research Service report summarizes developments in Pakistan and U.S.-Pakistan relations in 2011, including high-profile political assassinations, the Raymond Davis affair, and the killing of Osama bin Laden in Pakistan. It discusses key issues like terrorism, militancy, the Afghan insurgency, nuclear proliferation, and human rights. The capture and killing of bin Laden severely damaged trust between the countries and led some in Congress to question continued U.S. assistance to Pakistan. However, the U.S. still sees a stable, democratic Pakistan opposing extremism as vital to its interests in the region.
