Building and maintaining a credible minimum deterrent: Nuclear arsenals will be minimal enough to provide credible deterrence against adversaries.
A posture of "No First Use” (NFU): Nuclear weapons will only be used in retaliation against a nuclear attack on Indian territory or Indian forces anywhere.
Mutually Assured Destruction (MAD) on both sides: Nuclear retaliation to a first strike will be massive and designed to inflict unacceptable damage.
Non-use of nuclear weapons against non-nuclear weapon states (NNWS).
Commitment to the goal of a nuclear weapon-free world. Through global, verifiable and non-discriminatory nuclear disarmament.

Governance: Nuclear Command Authority (NCA) comprises a Political Council and an Executive Council.
- Political Council: chaired by Prime Minister, is the sole body (civilian political leadership) which can authorize the use of nuclear weapons for retaliatory attacks.
- Executive Council: chaired by National Security Advisor, provides inputs for decision making by NCA and executes the directives given to it by the Political Council.
Other aspects of the doctrine
- Option of retaliation with nuclear weapons in the event of a major chemical or a biological weapons (CBW) strike against India.
- Continuance of strict controls on export of nuclear and missile related materials and technologies and participation in the Fissile Material Cutoff Treaty (FMCT) negotiations.
- Moratorium on nuclear tests.

An infographic titled "Evolution (Key milestones)" outlines significant events in India's nuclear history. Milestones include India's first nuclear test in 1974, subsequent tests in 1998, the establishment of the National Security Advisory Board in 1999, and the release of an official nuclear doctrine in 2003.

India’s present nuclear standing vis-a-vis the global nuclear discourse:

Comprehensive Test Ban Treaty (CTBT): Prohibits all nuclear explosions; India did not sign due to lack of time-bound disarmament commitment by nuclear-weapon states.
Non-Proliferation Treaty (NPT), 1968: Aimed at limiting spread of nuclear weapons through three pillars of non-proliferation, disarmament, and peaceful use of nuclear energy.
- India did not sign the treaty due to biases as it divided world into “nuclear haves” and “nuclear have-nots”
Treaty on the Prohibition of Nuclear Weapons (TPNW): First legally binding agreement to ban nuclear weapons. India did not sign as it does not contribute to customary international law or set new standards.
Global Multilateral export control regimes
- India is a part:
  - Missile Technology Control Regime or MTCR (India joined in 2016)
  - Wassenaar Arrangement (India joined in 2017)
  - Australia Group (India joined in 2018)
- India is not a Part: Nuclear Suppliers Group (NSG) 1974 which was stablished post-India's 1974 nuclear test to prevent nuclear exports for weapon-making.

Factors underscoring need for India’s nuclear doctrine

Efficacy of No First Use: It remains the most debated element of India’s nuclear doctrine.

Aspect	Against NFU	In Favour of NFU
Risk of Initial Casualties	Could lead to unacceptably high initial casualties and damage to Indian population, cities, and infrastructure.	Contributes to India's strategic restraint posture and enables civil nuclear cooperation agreements and accommodation in multilateral nuclear export control regimes.
Ballistic Missile Defence (BMD)	An elaborate and costly BMD system required to defend against a first strike.	NFU helps India maintain a defensive and non-escalatory stance.
Effectiveness Against Nuclear neighbours	Ineffective against Pakistan, which is lowering its threshold with Tactical Nuclear Weapons (low-yield weapons to be used in their own territory against Indian forces).	A prudent and non-escalatory approach to managing tensions with China and contributes to regional stability.

How can the present nuclear doctrine be strengthened?

Dedicated defence technology programs on the lines of Integrated Missile Development Programmes can be started to ensure capacity building alongside technological developments.
Increasing flexibility on ‘massive retaliation’ commitment: It can lead to political actors to escalate the nuclear war, thus limiting the retaliatory options.
- To overcome this, some ambiguities could be introduced in the doctrine which enables the country to respond to threats like TNWs without it escalating to a full-fledged war.
Synchronizing with evolving Foreign Policy in light of geopolitical changes.
- Periodic review in a constantly evolving geo-strategic world order. For instance, American and Russian governments review their nuclear policy periodically.
- The intensification of China-Pakistan relations and their growing nexus with Russia, along with geopolitical instability across the globe demands calibrated review of India’s doctrine.
Building upon its status of a responsible nuclear power to emerge as a potential leader for promoting global nuclear non-proliferation and disarmament. Following efforts can be made by India in this regard:
- Engaging in multilateral discussions at the UN and other platforms such as Conference on Disarmament to voice the security and non-proliferation issues concerning states like itself.
- Conducting open and transparent dialogues on nuclear related issues with neighbouring countries as confidence building measures and convince more countries to adopt NFU.
  - Presently, China is the only other nuclear nation in addition to India that professes to follow the doctrine of NFU.
