Do armed drone programs decrease or increase terrorism? Existing studies on this question produce conflicting arguments and evidence. Drone optimists contend that armed drones reduce a country's vulnerability to terrorism, while pessimists claim that this military technology provokes higher levels of terrorism. Prior research focuses almost exclusively on one particular context: the short-term effect of the US drone program in Pakistan. However, armed drones have proliferated rapidly over the last decade and eighteen countries now possess this technology. The authors expand the scope of prior studies by leveraging new data to assess how obtaining armed drones and conducting drone strikes changed the degree to which all drone possessors experienced terrorism between 2001 and 2019.
