Discuss the efficacy of India’s ‘no first use’ policy (nuclear weapons) in the context of the evolving strategic challenges from its neighbours. (2020, 15 Marks)
India’s no first use (NFU) pledge, fixed in the Cabinet Committee on Security statement of 4 January 2003, promises nuclear use only in retaliation against a nuclear attack on Indian territory or forces, with an option against a major chemical or biological attack. Efficacy must be judged dyad by dyad: against Pakistan, which reserves first use, and against China, which shares the pledge but is arming fast.
The logic of the pledge
- Retaliation-only deterrence. Rajesh Rajagopalan (2019) argues that first use makes sense only for a state facing a non-nuclear existential threat, which India does not; Indian first use would only invite certain retaliation. Vipin Narang (Nuclear Strategy in the Modern Era, 2014) calls India’s posture assured retaliation.
- Control and cost. A retaliation-only force can stay largely de-mated under civilian command, and survivability, not numbers, becomes the sizing rule: about 190 warheads (SIPRI, 2026).
Against Pakistan: efficacy with a gap
- Nuclear stability holds. Balakot (2019) and Operation Sindoor (7–10 May 2025) punished terror attacks conventionally without nuclear use. Pakistan’s 10 May announcement of a National Command Authority meeting was denied within hours, and Prime Minister Narendra Modi then said India would not tolerate “nuclear blackmail”.
- The gap. NFU does not deter sub-conventional war, Glenn H. Snyder’s stability–instability paradox. Pakistan’s asymmetric escalation posture, the 70-km Nasr included, is built to make its weapons deter India’s conventional strength. Shyam Saran’s 2013 warning that a weapon’s label, tactical or strategic, is irrelevant narrows this loophole.
- Evolving challenges. A conventional Army Rocket Force Command (August 2025), the 27th Amendment (November 2025) creating a Chief of Defence Forces and an army-held National Strategic Command, and the Strategic Mutual Defence Agreement with Saudi Arabia (17 September 2025) raise Pakistan’s risk appetite.
Against China: efficacy through survivability
- China holds about 620 warheads; the Pentagon (December 2025) projects over 1,000 by 2030 and reports over 100 ICBMs loaded in new silo fields.
- Beijing’s white paper of 27 November 2025 reaffirmed NFU “at any time and under any circumstances”, so the dyad is doctrinally stable; the risk is the gap in capability.
- India’s answer is reach and survivability: the MIRVed Agni-5 (2024) and three SSBNs after INS Aridhaman (April 2026), though the K-4 missile is not confirmed as deployed.
- Collusion since Galwan (2020), with Chinese platforms in Pakistan’s hands during Sindoor, creates a two-front problem that “minimum” must cover.
Strains on credibility
- Shivshankar Menon’s “potential grey area” (Choices, 2016) and Rajnath Singh’s August 2019 remark that the future “depends on the circumstances” blur the pledge.
- Narang and Christopher Clary (International Security, 2018–19) see canisterisation and MIRVs as counterforce temptations.
- Bharat Karnad doubts that an untested thermonuclear yield deters China; some retired commanders would keep the pledge yet prepare for first use in extremis.
Conclusion
NFU has worked at the nuclear level: both dyads remain stable, the arsenal is capped and India’s standing has grown. It was never meant to stop terrorism, which India now answers conventionally. Efficacy now depends on capability: a deployed sea-based missile, survivable command against decapitation, and “assured” rather than “massive” retaliation wording.
