Last month, after years of indecision, Pakistan's military has launched a full-scale operation in the North Waziristan Tribal Agency aimed at eliminating terrorist bases and ending the region's lawlessness. In particular, the army wants to clear out foreign fighters who are using the territory as a base for various jihads around the Muslim world.
But by triggering yet another refugee crisis, the operation risks spreading the terrorist threat to other parts of Pakistan, including its largest city and commercial center, Karachi.
Operating from sanctuaries established in the tribal agency, various terrorist groups, in association with organizations elsewhere in the country, have already attacked Pakistan's four neighbors — Afghanistan, China, India, and Iran. Of the region's foreign fighters, Uzbeks belonging to the Islamic Movement of Uzbekistan have recently become the most visible threat, taking responsibility for the June 8-9 attack on Karachi's Jinnah International Airport, in which 30 people, including all 10 of the militants, were killed.
