Background

Overview

Understanding the global nuclear security architecture, India's stance on non-proliferation, challenges to the regime from emerging nuclear powers, and the role of international bodies in maintaining peace and security.

The Nuclear Non-Proliferation Regime is a global framework of treaties and agreements designed to prevent the spread of nuclear weapons, promote cooperation in the peaceful uses of nuclear energy, and work towards nuclear disarmament. The Treaty on the Non-Proliferation of Nuclear Weapons (NPT) serves as its foundational pillar, establishing a system of safeguards under the International Atomic Energy Agency (IAEA).
