📌 Background & Key Features
- Core pillars: No First Use (NFU) against nuclear weapon states; non-use against non-nuclear states; but a caveat allowing nuclear retaliation to a major chemical/biological attack.
- Credible minimum deterrence: India does not seek a nuclear arms race; force levels are kept at the minimum needed for assured retaliation.
- Massive retaliation: Any nuclear first strike on India or Indian forces anywhere will invite retaliation designed to inflict "unacceptable damage".
- Civilian control is enforced through the two-tier Nuclear Command Authority, keeping launch authority with the elected political leadership, not the military alone.
- India's global posture: India is a Nuclear Weapon State outside the NPT, but voluntarily observes a moratorium on further nuclear testing and supports universal, verifiable, non-discriminatory disarmament.

📰 Current Affairs Linkage (2025-26)
- NFU revision debate: Following Operation Sindoor (May 2025) against Pakistan-based terror infrastructure and repeated nuclear signalling by Pakistani officials, strategic commentators and some political leaders have renewed calls to reconsider NFU.
- SIPRI Yearbook 2026 estimates India now holds about 190 operationally deployable warheads (Pakistan ~170, China 600+), sharpening the "credible minimum deterrence in a two-front context" debate.
- India continues canvassing support for a universal, non-discriminatory Nuclear Weapons Ban/FMCT process at the UN, even as it stays outside the 2017 Treaty on the Prohibition of Nuclear Weapons (TPNW).
