D. Pakistan supported the Taliban when they ruled in neighboring Afghanistan from 1996-2001, but later became an ally of the United States when it led an invasion in 2001. Since their ouster, the Taliban and their al-Qaeda allies have found refuge in mountains along the Afghan-Pakistan border.
B. The extremely rough terrain makes it very difficult to stop Taliban and al-Qaeda fighters from freely crossing the Afghan-Pakistan border. U.S. forces in Afghanistan have used drone aircraft to track and bomb militants, sometimes bringing protests from Pakistani officials.
B. U.S. intelligence officials estimate that Pakistan has more than 100 nuclear weapons, at least twice as many as it had only four years ago. U.S., British and Russian officials worry these weapons could fall into the hands of Muslim terrorists, according to leaked diplomatic cables.
C. India and Pakistan have fought several wars over control of border areas, particularly the disputed territory of Kashmir. India first tested a nuclear weapon in 1974. Pakistan didn't test a weapon until 1998, but is believed to now have more warheads than India.
