The US military now fields more than 7,000 drones and 12,000 ground robots, a shift that has changed how it fights and where. Al Jazeera's Fault Lines team examines what that shift means in practice: fewer American casualties, less domestic political fallout, and lethal strikes carried out far from any declared battlefield, including inside Pakistan. Officials, military officers, and legal scholars weigh in on whether these strikes stretch the international laws of war past their intended limits, and on who answers for a death when the decision chain runs through software and remote operators instead of a soldier on the ground. The film also looks ahead to systems built with greater autonomy, tracing the debate over how much life-or-death authority should ever be handed to a machine rather than a person. Throughout, the reporting returns to a lack of public accountability: strikes conducted with little disclosure, and a legal framework that has not caught up with the technology already deployed.
