Ever since the 9/11 attacks, Pakistan's President Pervez Musharraf has doggedly made the case to Washington that he is the finger in the dike holding back a wave of Islamic extremism. Having successfully argued his own indispensability, General Musharraf has reaped billions of dollars in economic aid and arms sales — while encountering little challenge from Washington over his backsliding from steps toward democratic rule. Military aid to Pakistan grew from under $10 million in the three years prior to 9/11 to more than $4 billion in the three years after. But now it is political protest, fueled by Musharraf's steps to consolidate and extend his power, that is washing over Pakistan. That is presenting the U.S. with a classic dilemma of the war on terrorism: Does a key leader's security value outweigh his authoritarian practices? Earlier this month, Musharraf suspended the country's Supreme Court chief justice. Ever since, Pakistan's middle classes - one of the chief beneficiaries of the military leader's eight-year rule - have taken to the streets. Also fueling the uproar are suspicions that Musharraf is paving the way to another term as both president and chief military leader. Musharraf cited abuse of power" when he suspended Chief Justice Iftikhar Muhammed Chaudhry on March 9. Chaudhry had also expressed his view that it was not legal under the constitution for Musharraf to seek another presidential term while remaining the Army chief. The Bush administration has ... has expressed concern over some clashes that have turned violent but has reiterated support for Musharraf as a valuable ally in the war on terror.
