Background

Overview

Understanding nuclear deterrence is crucial for analyzing global security dynamics, arms control treaties, non-proliferation efforts, and the foreign policy decisions of nuclear-armed states like India, Pakistan, China, and North Korea. It directly impacts regional stability and international power balances.

Nuclear deterrence is a military strategy in which one party discourages an attack by another party through the threat of using nuclear weapons. It relies on the principle that the costs of an attack (retaliation with devastating nuclear force) would outweigh any potential benefits, thereby preventing the initial attack.
