Autonomous Lethal Weapons: 128 States Take a Major Step Towards International Regulation

Sunday 06 September 2026 - 08:59

After more than ten years of discussions, international negotiations on autonomous lethal weapons have reached a significant milestone. In Geneva, 128 states reached a consensus on a text proposing a common definition of these weapon systems and emphasizing the need to maintain meaningful human control over their use.

The agreement does not yet constitute a treaty and imposes no legally binding obligations. However, it could serve as a starting point for future international negotiations as artificial intelligence and autonomy gain traction in military technologies.

A Common Definition After Over a Decade of Debate

The consensus was achieved on Saturday within the Group of Governmental Experts (GGE) of the Convention on Certain Conventional Weapons (CCW), after negotiations that continued late into the night.

Autonomous lethal weapon systems, or ALWs, refer to weapons capable, to varying degrees of autonomy, of identifying and engaging targets with limited or no direct human intervention at the time of action.

The search for a common definition is a crucial issue. It must allow states to precisely determine which technologies fall within the scope of future international regulations.

Human Control at the Core of the Text

The document adopted in Geneva particularly stresses the need to maintain meaningful human control over the systems in question. It also reiterates that their design and use must comply with the principles of international humanitarian law.

For advocates of stricter regulation, this aspect is fundamental. The use of systems capable of autonomously selecting or engaging targets raises questions about accountability, the distinction between civilians and combatants, and the ability of operators to anticipate decisions made by a machine.

The Dutch Foreign Minister, Tom Berendsen, whose country is chairing the negotiations, hailed from Geneva a "significant step" in light of the rapid evolution of military technologies.

ICRC Calls for Binding Rules

The International Committee of the Red Cross (ICRC) believes that the development of autonomous weapons without a sufficiently restrictive framework poses major legal, ethical, and humanitarian issues.

The organization advocates for a ban on systems whose behavior would be unpredictable, as well as those designed or used to directly exert force against individuals.

This position illustrates the gap that remains between the search for consensus among states and the demands of humanitarian organizations for binding international norms.

A Step Before Possible Treaty Negotiations

The text adopted in Geneva is therefore just a first step. The next deadline will be at the CCW Review Conference scheduled for November.

States will then need to determine the next steps following the consensus achieved by the GGE. Among the options is the opening of formal negotiations aimed at developing an international instrument governing the design, development, and use of autonomous weapons.

However, the path towards a potential treaty remains uncertain. Differences among states regarding the acceptable level of autonomy, the degree of required human control, and the categories of systems that should be banned or regulated could further complicate discussions.

Artificial Intelligence Accelerates the Urgency of the Debate

The consensus comes in a context where military technologies are evolving rapidly. Advances in artificial intelligence now allow for systems capable of analyzing information, identifying targets, and assisting or even automating certain operational decisions.

For the 128 states gathered in Geneva, the challenge now is to transform this initial diplomatic convergence into sufficiently precise rules to accompany this technological evolution.

The next step could therefore be decisive: moving from a common definition to a true international framework capable of setting limits on the autonomy applied to weapons.
