Q. Does India's MIRV capability undermine its declared 'Credible Minimum Deterrence' posture? Critically analyse. (15 marks, 250 words)

India's 2003 nuclear doctrine rests on Credible Minimum Deterrence (CMD) and No-First-Use (NFU), promising "massive" retaliation only after being struck [1]. The maiden Agni-5 MIRV test (Mission Divyastra, 11 March 2024) and the 2026 Advanced Agni MIRV trial raise whether "multiple warheads per missile" strains the "minimum" ideal [2][3].

How MIRV appears to dilute the posture - Warhead multiplication: one bus dispersing several independently-targeted warheads inflates numbers, testing the word minimum [2]. - First-strike incentive: MIRVs are attractive counterforce targets, historically seen as destabilising and arms-race-inducing. - Regional signalling: joining the elite MIRV club (US, Russia, China, UK, France) may spur adversary build-up in the Indo-Pacific [2].

How MIRV actually strengthens CMD - Survivability, not expansion: MIRV lets fewer surviving missiles penetrate Ballistic Missile Defence shields, making assured second-strike credible — the "credible" in CMD [3]. - Doctrinal continuity: NFU and civilian Nuclear Command Authority control remain intact; it is a qualitative, not doctrinal, shift [4]. - Restraint record: indigenous DRDO development within a voluntary test moratorium, no NPT/CTBT violation, signals responsible stewardship [3].

MIRV thus refines rather than repudiates CMD: it upgrades credibility to keep deterrence honest against evolving defences, while "minimum" stays a policy choice, not a technical ceiling. Anchoring MIRV numbers to genuine second-strike sufficiency—and pairing it with confidence-building measures—will preserve strategic stability consistent with India's restraint-based doctrine.
