Guest host Dr. Chris Moran of Warwick University (UK) sat down with his colleague, Dr. Trevor McCrisken, for a SpyCast on the role of drones in modern surveillance, warfighting, and counterterrorism. McCrisken, whose biography can be found here, discusses the weaponization of drones, the targeted killing program of the Bush and Obama administrations, the perception in the West that the drone war is “costless”, and the possibility of what he calls the “perpetual war” against global terrorism.
