Debate Grows Over Reviewing India's 2003 Nuclear Doctrine

India's nuclear doctrine sits outside the global non-proliferation architecture built around the Nuclear Non-Proliferation Treaty (NPT), 1968. The NPT recognises only five Nuclear Weapon States: the US, Russia, UK, France and China. India, along with Pakistan and Israel, never signed the treaty and remains outside this recognised category despite possessing nuclear weapons. India first demonstrated nuclear capability with the Smiling Buddha test in 1974, describing it as a peaceful nuclear explosion, and became an overt nuclear weapons state after the Pokhran-II tests of 1998. Because India built its arsenal outside the NPT framework, it also had to construct its own declaratory doctrine independently, rather than inheriting one from a treaty regime.

The doctrine's formal shape came from the National Security Advisory Board's 1999 Draft Nuclear Doctrine, which first proposed credible minimum deterrence as India's guiding principle. This was operationalised through a Cabinet Committee on Security decision on January 4, 2003. The resulting doctrine rests on No First Use (NFU), a promise of massive retaliation to a nuclear attack causing unacceptable damage, an exception allowing nuclear retaliation against a major biological or chemical weapons attack, a survivable second-strike capability, and firm civilian political control exercised through the Nuclear Command Authority. India's civilian and military nuclear facilities are also kept administratively separate. The Additional Protocol it has ratified with the IAEA brings only civilian reactors under international safeguards, leaving military facilities outside inspection so the doctrine's deterrent capability remains intact.
