While the US drone-strikes program is under renewed scrutiny, remotely piloted aircraft are but one element of modern precision-strike capability. Military action in Mali, Libya and elsewhere has demonstrated the continuing, critical reliance on advanced technological capabilities in modern Western intervention. This raises a number of important questions about the thresholds for military intervention, the way it is carried out, and its consequences; in particular, whether ethical, legal, and policy frameworks have kept up with the pace of technological change, and how this affects the behavior of those responsible for policy and for its implementation on the ground. Although intervention is a political act, and many of the activities that constitute contemporary military intervention are not new, some argue that unmanned capabilities will lead to a shift in the ease and conduct of warfare. This report considers the issues of media and public perception, including new data on British attitudes towards drone strikes; the technological, ethical and legal issues of unmanned capability; and a detailed assessment of targeted killing as a strategy.
