Autonomous weapons — those weapons which can select and engage targets without human involvement — herald perhaps the most fundamental change in warfare in generations. The rise of autonomous weapons has sparked a robust international debate centered on one fundamental question: are the current laws of armed conflict sufficient to govern autonomous weapon systems? Positions span the spectrum from a call for preemptive prohibition to arguments that current legal norms are adequate to regulate these future weapon systems. While autonomous features may give rise to circumstances in which the application of the law is rendered uncertain or difficult, the current normative legal framework is sufficient to regulate the new technology.
This article considers the entirety of positions and seeks to present a comprehensive, objective discussion of the relevant issues in international law. In the course of this examination, the article reaches two broad conclusions. First, autonomy is less a technology as it is a capability comprised of multiple technologies. Given this fact, “autonomous weapons” cannot be considered a homogeneous category of weapons that complies, or not, with the law of armed conflict. Rather, whether a given system meets the requirements of this body of law will depend on the system and the manner in which it is used. Second, the normative framework established by the law of armed conflict is sufficient to ensure the lawful operation of most types of weapons employing autonomous technologies.
