The Legal Status of Nuclear Non-Proliferation in International Law: A Critical Analysis of Prohibition, Control, and Disarmament Mechanisms

Abstract

The proliferation of nuclear weapons remains one of the most significant challenges to international peace and security in the twenty-first century. Since the advent of nuclear weapons following the Second World War, the international community has sought to establish legal and institutional frameworks aimed at preventing the spread of nuclear weapons while promoting peaceful uses of nuclear energy and advancing the goal of nuclear disarmament. This article examines the legal status of nuclear non-proliferation within contemporary international law, with particular emphasis on the interconnected concepts of prohibition, control, and disarmament. Employing a descriptive-analytical methodology and relying on treaty law, customary international law, judicial decisions, and the practice of international organizations, the study evaluates the effectiveness of the existing non-proliferation regime. Special attention is devoted to the Treaty on the Non-Proliferation of Nuclear Weapons (NPT), the safeguards system of the International Atomic Energy Agency (IAEA), and the role of the United Nations in promoting disarmament and preventing proliferation. The article further analyzes the legal and political challenges facing the regime, including the persistence of nuclear deterrence doctrines, unequal obligations between nuclear and non-nuclear weapon states, and emerging threats associated with technological developments and regional security rivalries. The findings suggest that while the current legal framework has achieved significant success in limiting the spread of nuclear weapons, structural inequalities and enforcement deficiencies continue to undermine its long-term effectiveness. The article concludes that strengthening verification mechanisms, enhancing compliance procedures, and promoting universal commitment to nuclear disarmament are essential for the future credibility of the international non-proliferation regime.
