"The most explosive question about the Taliban resurgence here along the border between Afghanistan and Pakistan is this: Have Pakistani intelligence agencies been promoting the Islamic insurgency?"
"...Pakistani intelligence agencies ... have been supporting a Taliban restoration, motivated not only by Islamic fervor but also by a longstanding view that the jihadist movement allows them to assert greater influence on Pakistan's vulnerable western flank."
"At Jamiya Islamiya, a religious school here in Quetta, Taliban sympathies are on flagrant display, and residents say students have gone with their teachers' blessings to die in suicide bombings in Afghanistan."
"The Pakistani military and intelligence services have for decades used religious parties as a convenient instrument to keep domestic political opponents at bay and for foreign policy adventures"
"The Inter-Services Intelligence once had an entire wing dedicated to training jihadis ... Today the religious parties probably have enough of their own people to do the training"
"Pakistan has long seen jihadi movements like the Taliban as a counter to Indian and Russian influence next door in Afghanistan"
