In a historic move, the United Nations General Assembly has adopted a resolution emphasizing the applicability of international law to lethal autonomous weapons systems. While this marks a significant step, member states did not reach a consensus for a total ban on such technologies. The vote saw 164 nations supporting resolution L.56, which addresses both the opportunities and the challenges presented by emerging technologies like artificial intelligence (AI) and autonomy in weaponry. The resolution reiterates that the U.N. Charter, international humanitarian law, and international human rights law are relevant to autonomous weapons systems.
Introduced by Austria with the support of 43 co-sponsoring countries, this resolution is the first of its kind to focus entirely on autonomous weapons. The final text expresses concerns regarding potential adverse effects but ultimately stops short of demanding a prohibition. Notable supporters included the United States, the United Kingdom, Ukraine, and Germany. Conversely, five countries—India, Russia, Belarus, Mali, and Niger—voted against the resolution, while eight countries, including China, Israel, Iran, Saudi Arabia, North Korea, Syria, Turkey, and the United Arab Emirates, chose to abstain.
The resolution lacks clarity on the precise definition of autonomous weapons systems, reflecting the ongoing evolution of their capabilities. Currently, militaries worldwide utilize drones—such as those operated by China, Russia, and Ukraine—which are primarily human-controlled but may possess some autonomous functions. There are also drone swarms, which consist of small, bomb-laden drones designed to coordinate attacks on targets, and unmanned combat vehicles like the U.S.'s test vehicles from 2021, as well as Russia's Uran-9 UCGV, recently integrated into the military before the onset of the conflict in Ukraine. Additionally, there are concepts involving quadrupedal robots like Boston Dynamics' Spot, which the company has pledged not to deploy in warfare. However, competitors like Ghost Dynamics are supplying similar robots for military applications.
In light of the resolution, member states have been urged to engage in further discussions to establish a common understanding of the terminology and the broader implications of autonomous weapons systems. The resolution requests that the U.N. Secretary-General gather insights from Member States regarding autonomous weapons and prepare a report on the findings. Notably, the topic will be featured in the agenda for the General Assembly's 79th session scheduled for September 2024.
In response to the vote, the advocacy group Stop Killer Robots remarked that the support for the resolution illustrates a widespread desire among nations to advance toward the establishment of new international legal frameworks. This development aligns with recent appeals from the U.N. Secretary-General António Guterres for the creation of legally binding regulations on autonomous weapons by 2026, a proposition made during the inaugural U.N. Security Council meeting focused on AI held in July.
Discussions regarding international regulations for autonomous weapons have been taking place for nearly a decade, with an attempted ban in 2021 ultimately defeated by major powers. Meanwhile, militaries have continued to advance their autonomous weapons initiatives, with the United States allocating approximately $18 billion for related research between 2016 and 2020. The Pentagon has also expanded its AI programs to counter threats, particularly from China, such as through the Replicator program, which involves deploying numerous small, cost-effective autonomous drones to overwhelm designated targets.
