Nuclear Deterrence and Legal Norms: Comparing the Approaches of Pakistan and Russia

This paper offers a comparative legal analysis of nuclear deterrence as practiced by two non-Western nuclear powers — the Russian Federation and the Islamic Republic of Pakistan — focusing on how each state's strategic doctrine interacts with international legal norms. While Russia has increasingly deployed nuclear rhetoric as a tool of coercion during its war against Ukraine, Pakistan uses deterrence to offset conventional asymmetry in its longstanding rivalry with India. By analyzing their respective doctrines, signaling practices, and the legal grey zones they exploit, the paper reveals how nuclear deterrence is shifting from a principle of conflict prevention toward a mechanism of political intimidation and normative erosion. The study highlights gaps in the current international legal framework, particularly in distinguishing lawful deterrence from unlawful nuclear coercion. Drawing on examples from both regional contexts, it emphasizes the need for doctrinal transparency, legal accountability, and regional confidence-building mechanisms. Ultimately, this paper argues that the legitimacy of nuclear deterrence must be re-grounded in legal responsibility and that deterrence should not serve as a shield for aggression, but as a constrained and regulated last resort.
