Ambassador Kurt Volker makes a cogent and balanced case, particularly from a moral standpoint, for more circumspection in ourthe United States’ reliance on the use of drone strikes to degrade or eliminate terrorist capabilities. However, he neglects one critical argument. By killing terrorists instead of capturing them, admittedly a significantly more difficult task, the United States deprives itself of vital intelligence which could help disrupt future acts of terrorism. Former senior CIA official Jose Rodriguez and others have made this case very eloquently. The moral argument against over-reliance on the use of drones notwithstanding, our country would derive much greater benefit from capturing and interrogating these individuals instead of simply killing them.
