Background

Overview

This concept is fundamental to understanding global security challenges, international relations, the role of international law and institutions, and India's foreign policy stance on nuclear issues (e.g., NPT, CTBT).

Nuclear proliferation refers to the spread of nuclear weapons, fissionable material, and weapons-applicable nuclear technology and information to states not recognized as 'nuclear-weapon states' under the Treaty on the Non-Proliferation of Nuclear Weapons (NPT). Disarmament aims to reduce or eliminate such weapons, often through international treaties and verification regimes.
