Nuclear Proliferation Policy and International Security

The challenge of limiting the spread of nuclear weapons remains central to global security, anchored in a web of legal treaties, diplomatic institutions and technological oversight. The cornerstone of international policy is the Non-Proliferation Treaty, which seeks to prevent horizontal proliferation while promoting peaceful nuclear energy. Successive augmentations – notably the comprehensive safeguards administered by the International Atomic Energy Agency, export-control regimes such as the Nuclear Suppliers Group and regional arms-control arrangements – have aimed to constrain sensitive technologies without stifling legitimate civilian applications. Nevertheless, geopolitical tensions, latent nuclear capabilities and the diffusion of advanced enrichment and reprocessing techniques sustain a persistent risk that new actors may join the nuclear club. Contemporary policy debates therefore navigate a delicate balance between reinforcing normative barriers, adapting verification mechanisms to emerging technologies, and integrating non-proliferation objectives with wider security imperatives including counter-terrorism and regional stability. At the same time, evolving strategic doctrines and modernised arsenals have transformed the calculus of deterrence, underscoring the need for robust crisis management, transparency measures and dialogue to avert misperception and escalation in an increasingly multipolar world.
