Although the U.S. has been the world's pre-eminent user of unmanned aerial vehicles (UAVs), otherwise known as drones, our technological advantage is eroding as drone technology spreads across the world, with some 80 countries now building active drone programs. This new arms race in drones is sure to have important strategic consequences both in surveillance as well as war and raises important questions about the use of drones by the U.S. and others. Our guests will debate U.S. reliance on drones, the ethics of targeted killings, and the future roles of autonomous systems.
