I. INTRODUCTION
In recent years, the rapid advancement of military technology has led to the emergence of artificial intelligence-based autonomous weapon systems, creating a new paradigm that challenges the traditional logic of the law of war. These systems can make target selection and firing decisions without human supervision, deepening both ethical and legal questions. International law evaluates the actions of a belligerent party within the framework of intent, foresight, nature, and command control. However, elements such as the uncertainty arising from the learning process of artificial intelligence algorithms, data-driven biases, and susceptibility to sensor errors render the concepts that play a central role in legal evaluations ambiguous. Questions such as who is responsible when a system misclassifies a target or uses disproportionate force, at what stage the commander assumes responsibility, and how the element of intent is determined, pose difficult legal problems to answer. In this context, this brief aims to clarify how autonomous weapon systems are positioned under international law.
II. FOUNDATIONS OF STATE RESPONSIBILITY AND THE CHALLENGE OF AUTONOMOUS WEAPONS
Under international law, the establishment of state responsibility hinges upon the attribution of an unlawful act to the state. Actions executed by an autonomous system do not absolve the state of its responsibility, as a machine lacks legal personhood and cannot be recognized as a perpetrator under international law. The ultimate responsibility is vested in the state that develops, employs, or exercises control over the system.
However, the intricate and inherently unpredictable nature of algorithms predicated on deep learning poses challenges to human operators in terms of foreseeing and maintaining control over the system in all conceivable scenarios. This gives rise to ongoing discourse regarding the precise scope of responsibility. This uncertainty is of particular salience in the context of the law on the use of force, which governs the legitimacy of employing coercive measures. States bear the risk of autonomous systems perpetrating unintended attacks stemming from malfunctions or false positives. Contemporary international law operates within an objective framework of state responsibility, wherein the increasing autonomy of systems does not attenuate the attribution of conduct to the state. To the contrary, it imposes more extensive obligations of supervision and due diligence on states throughout the processes of designing, testing, and deploying autonomous systems in operational environments.
III. JUS AD BELLUM: THE IMPACT OF AUTONOMOUS SYSTEMS ON THE USE OF FORCE
Consistent with the framework of jus ad bellum, the lawful resort to force is predicated upon the exercise of the right to self-defense, the explicit consent of the state against which force is directed, or authorization duly conferred by the United Nations Security Council. In this context, the utilization of autonomous weapon systems does not, in itself, render the use of force unlawful. Nevertheless, the accelerated tempo of decision-making processes, coupled with the reduction in costs associated with military personnel engendered by these systems, may effectively diminish the threshold at which states are inclined to resort to force. Such a tendency undermines the efficacy of deterrence mechanisms and may facilitate a proclivity towards low-intensity or limited-cost operations.
Moreover, engagements initiated as a consequence of sensor detection anomalies, data processing aberrations, or misclassifications attributable to environmental variables by autonomous systems impede the definitive identification of the party responsible for instigating the initial act of aggression. This concatenation of circumstances, when coupled with heightened tensions arising from miscalculations in crisis management, may precipitate escalation dynamics, potentially triggering broader regional or even global conflict. Therefore, the advent of autonomous systems introduces novel risks that serve to complicate the practical implementation of the jus ad bellum regime.
IV. JUS IN BELLO: PRINCIPLES OF DISTINCTION, PROPORTIONALITY AND HUMANITY
Jus in bello, governing the application of the law of war, comprises principles that delineate permissible means and methods of warfare. Central to these principles are the rules of distinction, proportionality, and the avoidance of superfluous injury or unnecessary suffering. The implementation of these principles in the context of autonomous weapon systems engenders significant legal debate, primarily due to the inherent limitations of current technologies.
Specifically, biases in datasets, sensor anomalies, performance variability contingent upon environmental conditions, and inconsistencies in target recognition exhibited by artificial intelligence-based systems impede the reliable differentiation between combatants and non-combatants. This situation presents a direct challenge to the foundational tenet of international humanitarian law, which prioritizes the protection of civilian populations.
Article 36 of Additional Protocol I to the Geneva Conventions places an obligation on states to assess the compatibility of new weapon systems with extant international legal obligations. Given their intricate decision-making processes and the potential for unpredictable behavior, autonomous weapon systems necessitate particularly rigorous examination in this regard. Moreover, Article 51 of the Protocol proscribes the use of weapons that are inherently indiscriminate, incapable of distinguishing between military objectives and civilian objects. The capacity for independent operation exhibited by autonomous systems, coupled with the opacity of algorithmic decision-making, generates substantial legal uncertainty as to whether these fundamental criteria can be adequately satisfied.
V. ARTIFICIAL INTELLIGENCE, HUMAN CONTROL AND THE CHAIN OF RESPONSIBILITY
The capacity for autonomous weapon systems to execute decision-making processes largely independent of human intervention presents novel challenges to established responsibility frameworks under international law. In circumstances involving unlawful engagements, the allocation of responsibility among actors such as the commanding officer, system developer, manufacturing entity, software engineer, or individuals responsible for data set creation remains ill-defined. The inherent opacity of artificial intelligence models and the limited explicability of algorithmic determinations further obfuscate the establishment of a clear chain of responsibility.
Consequently, numerous states and subject-matter experts advocate for the implementation of “meaningful human control” as a normative imperative in the deployment of autonomous systems. However, international consensus remains elusive regarding the requisite level of human control, the temporal parameters governing the possibility of human operator intervention, and the specific conditions under which a commanding officer assumes legal responsibility.
VI. LACUNAE IN INTERNATIONAL LAW AND REGULATORY DEBATES
The absence of a specific, binding international legal instrument governing autonomous weapon systems engenders a notable lacuna in the existing legal framework, particularly in light of the accelerated pace of technological advancements in this domain. Discussions in the international community revolve around three main approaches: complete prohibition of the systems, limited permission within an ethical framework, or not enacting additional regulations under the assumption that the existing normative order is sufficient. These approaches reflect different assessments regarding the level of regulation required in the face of the legal responsibility, control, and predictability issues of autonomous weapons.
While a large part of European states supports the creation of norms that mandate meaningful human control, states with high technological capabilities such as the United States, Russia, and China advocate for a more flexible approach, arguing that a binding regulation could limit their competitive advantages. There are also disagreements on the extent to which the Geneva Conventions and Additional Protocols can be applied to automatic and autonomous systems. These normative ambiguities impede the reinforcement of accountability mechanisms and heighten the potential for states to compromise international peace and security through the unfettered augmentation of their military capabilities.
VII. TURKISH PERSPECTIVE: NATIONAL LAW, TECHNOLOGY POLICIES, AND INTERNATIONAL OBLIGATIONS
Within the broader legal and technological landscape governing unmanned systems and artificial intelligence-based platforms, Türkiye’s approach is generally characterized by its attentiveness to international developments and its engagement with established global norms. As a state party to the 1949 Geneva Conventions, Türkiye operates within the parameters of international humanitarian law, including the principles reflected in Article 36 of Additional Protocol I, which form part of the legal context relevant to the assessment of emerging weapon systems.
Although a specific national legal instrument directly regulating autonomous weapon systems has not yet been adopted, the existing legal framework, policy discussions, and institutional practices indicate that Türkiye remains observant of evolving international debates and comparative regulatory trends in this domain. In the context of defense exports, academic analyses often draw attention to the potential legal implications that may arise under international law when exported systems are employed by other states, a subject that continues to be examined within the literature on state responsibility.
Türkiye’s expanding regional profile and ongoing technological advancements in its defense sector create a setting in which various legal and operational questions—such as the integration of command-and-control mechanisms into autonomous systems, the adjustment of engagement parameters, and the articulation of minimum levels of human involvement—are likely to remain relevant to future scholarly and policy assessments. In this regard, Türkiye’s trajectory is understood as one that evolves in parallel with international legal discussions, technological progress, and broader global practices, rather than reflecting any predetermined or declaratory national commitment.
VIII. CONCLUSION
Autonomous weapon systems represent a technological transformation that has the potential to fundamentally transform both the normative and practical orders of international law. These systems do not create a new perpetrator; the responsibility for unlawful acts is still attributed to the state. However, the inherent technical uncertainties stemming from autonomy present formidable challenges, particularly with respect to the application of the law of war, and intensify discourse concerning the continued adequacy of traditional legal doctrines. Although the use of autonomous weapons does not directly create a legitimacy problem in terms of the law on the use of force, the potential to lower the threshold for resorting to force and to lead to easier escalation of conflicts poses a significant risk that threatens international stability.
This issue assumes heightened importance for Türkiye, given its concomitant international obligations and the rapid advancements occurring within its domestic defense technology sector, which collectively necessitate the urgent establishment of a holistic, predictable, and legally consistent framework at the national level. This framework should not be confined solely to technical standards or operational protocols; rather, it must encompass explicit regulations pertaining to principles of responsibility, control mechanisms, transparency obligations, and ethical imperatives.
In conclusion, the introduction of artificial intelligence-supported autonomous systems onto the battlefield has initiated an irreversible trajectory, rendering it imperative to institute a binding, transparent, and universally applicable regulatory regime capable of adapting to rapid technological change. This regulation should reflect the technical capacity differences, security concerns, and ethical sensitivities of states in a balanced manner; it should also be designed with the flexibility to adapt to rapidly changing technological developments. Otherwise, the uncontrolled proliferation of autonomous weapons will erode the fundamental principles of the international order, creating new and unpredictable risks.
