President Bush held an emergency meeting of his top foreign policy aides yesterday to discuss the deepening crisis in Pakistan, as administration officials and others explored whether Thursday's assassination of opposition leader Benazir Bhutto marks the beginning of a new Islamic extremist offensive that could spread beyond Pakistan and undermine the U.S. war effort in neighboring Afghanistan.
U.S. officials fear that a renewed campaign by Islamic militants aimed at the Pakistani government, and based along the border with Afghanistan, would complicate U.S. policy in the region by effectively merging the six-year-old war in Afghanistan with Pakistan's growing turbulence.
"The fates of Afghanistan and Pakistan are inextricably tied," said J. Alexander Thier, a former United Nations official in Afghanistan who is now at the U.S. Institute for Peace.
