U.N. Alarmed By Surge In Civilian Casualties In Afghanistan-WAPO March 9, 2011
As for PREDATOR, Pak Sher, you haven't got an actual clue. Nobody does except the Taliban and C.I.A. and neither are talking. Ms. Farhat Taj and others, though, believe the numbers of innocent civilians killed are far less than Pakistani nationalists trumpet here and elsewhere. She and others from the Aryana Institute have at least conducted serious research among pashtun I.D.P.s inside refugee camps and surveys among those inside FATAville.
None of that matters, though. Most here prefer believing that PREDATOR is ineffective. Suits their pre-conceived notions despite whatever Kayani says otherwise in private with our officials.
