Report collecting statistics from a variety of sources on casualties sustained during Operation Enduring Freedom (OEF), which began on October 7, 2001. OEF actions take place primarily in Afghanistan; however, OEF casualties also includes American casualties in Pakistan, Uzbekistan, Guantanamo Bay (Cuba), Djibouti, Eritrea, Ethiopia, Jordan, Kenya, Kyrgyzstan, the Philippines, Seychelles, Sudan, Tajikistan, Turkey, and Yemen.

This report discusses Pakistan's nuclear arsenal, which probably consists of approximately 110-130 nuclear warheads, although it could have more. Pakistan's nuclear arsenal is widely regarded as designed to dissuade India from taking military action against Pakistan, but Islamabad's expansion of its nuclear arsenal, development of new types of nuclear weapons, and adoption of a doctrine called "full spectrum deterrence" have led to concern about an increased risk of nuclear conflict between Pakistan and India.

This report discusses key U.S. interests regarding Pakistan, especially as related to counterterrorism and U.S. foreign assistance.

Pakistan is a strategically important country and home to one of the world’s largest Muslim populations. In October 1999, Pakistan’s Chief of Army Staff Gen. Pervez Musharraf replaced Prime Minister Nawaz Sharif in a bloodless coup. In the wake of the military overthrow of the elected government, Islamabad faced considerable international opprobrium and was subjected to automatic coup-related U.S. sanctions. The September 2001 terrorist attacks on the United States and Musharraf’s ensuing withdrawal of support for the Afghan Taliban regime, however, had the effect of greatly reducing Pakistan’s international isolation. Congress removed restrictions, and large-scale U.S. aid to the country resumed, in the final months of 2001.

A stable, democratic, economically thriving Pakistan is vital to U.S. interests in Asia. Key U.S. concerns regarding Pakistan include regional terrorism; weapons proliferation; the ongoing Kashmir problem and Pakistan-India tensions; human rights protection; and economic development. A U.S.-Pakistan relationship marked by periods of both cooperation and discord was transformed by September 2001 terrorist attacks on the United States and the ensuing enlistment of Pakistan as a pivotal ally in U.S.-led counterterrorism efforts. The top U.S. officials regularly praise Islamabad for its ongoing cooperation, although doubts exist about Islamabad’s commitment to some core U.S. interests in the region.
