Editors’ note: This is the fifth post in a series dedicated to Lethal Autonomous Weapons Systems (LAWS) and the questions of human oversight and legal accountability under international humanitarian law. Previous posts have focused on LAWS, China, Russia, and the U.S.
As artificial intelligence (AI) rapidly transforms the modern battlefield, the core principles of international humanitarian law (IHL) are confronting their most significant tests of the twenty-first century. Consequently, the emergence of lethal autonomous weapons systems (LAWS)—weapon systems that can select and engage targets without meaningful human control—has generated sustained discussion within the Group of Governmental Experts (GGE) on LAWS operating under the Convention on Certain Conventional Weapons (CCW).
This post analyses the European approach, which does not equate to a unified “European Union (EU) approach.” Although the EU has articulated a shared institutional position on the applicability of IHL and the necessity of meaningful human control over LAWS, defense and security policy remain core areas of national competence. Collectively, member States make the EU the world’s third-largest defense spender after the United States and China. European States have consistently affirmed that IHL remains fully applicable to such systems and that humans must retain the capacity to make legal judgments over the use of lethal force. However, while a common EU baseline exists on the necessity of human oversight, national positions reveal important differences in emphasis, preferred legal instruments, and tolerance for varying degrees of autonomy, variations that carry implications not only for ongoing CCW deliberations but also for future European defense cooperation and the broader evolution of IHL in an era of autonomous weaponry.
