“…For two decades, the US has used unmanned aerial vehicles (UAVs) -"drones" -as platforms for small-scale airstrikes on specific individuals, increasingly relying upon this method of counterterrorism and counter-insurgency, with numbers of strikes and casualties now in the thousands. The evolution of targeted killing in the US is already the subject of a number of recent examinations (see, among others, Carvin, 2015;Fuller, 2017;Grayson, 2012Grayson, , 2016Zenko, 2013), and these establish key ways in which changing legal discourse and re-conceptualizations of the geography of counterterrorism were facilitating factors. 1 This concerns the particular definition of assassination under international law (Beres, 1991;Pickard, 2001;Thomas, 2001), questions of imminence and pre-emption (Gordon, 2006;Kasher and Yadlin, 2005), the space in which a formal armed conflict is occurring, and the status of combatants (Blum and Heymann, 2010).…”
