Killer Robots

"Killer robots" is the advocacy shorthand for lethal autonomous weapons systems (LAWS) — weapons that, once activated, can identify, select, and apply force to targets without further human intervention. The term was popularised by the Campaign to Stop Killer Robots, an NGO coalition launched in April 2013 and coordinated by Human Rights Watch alongside groups such as Article 36, PAX, and Mines Action Canada.

The category spans a spectrum: from existing defensive systems with autonomous modes (e.g., point-defence guns that intercept incoming missiles) to envisioned offensive platforms — armed drones, ground vehicles, or loitering munitions — that would make kill decisions through machine learning and sensor fusion. Loitering munitions such as the Israeli Harpy and the Turkish STM Kargu-2, the latter referenced in a 2021 UN Panel of Experts report on Libya, are frequently cited as early examples operating at the edge of autonomy.

Diplomatic discussion has taken place since 2014 under the Convention on Certain Conventional Weapons (CCW) in Geneva, where a Group of Governmental Experts (GGE) on LAWS was established in 2016. The GGE adopted eleven Guiding Principles in 2019, affirming that international humanitarian law (IHL) applies fully to such systems and that human responsibility must be retained. Progress toward a binding treaty has stalled, with states such as Russia and the United States opposing prohibition, while Austria, Brazil, New Zealand, and many states of the Global South support new legally binding rules. In December 2023, the UN General Assembly adopted Resolution 78/241, its first resolution on autonomous weapons, requesting the Secretary-General to seek states' views.

Core legal and ethical concerns include: compliance with IHL principles of distinction, proportionality, and precaution; the accountability gap when machines err; the risk of lowering thresholds for armed conflict; and proliferation to non-state actors. UN Secretary-General António Guterres has repeatedly called autonomous weapons "morally repugnant" and urged a treaty by 2026.
