Discuss the role of disruptive technologies in eroding the stability of nuclear deterrence, with reference to India.

India's nuclear doctrine, operationalised by the Cabinet Committee on Security on 4 January 2003, rests on credible minimum deterrence, no first use (NFU) and assured retaliation under civilian control [1]. Deterrence stability assumes two things: a retaliatory force that survives, and leaders who have time to decide. Disruptive technologies erode both.

How disruptive technologies destabilise deterrence

• Compressed decision time: faster and more precise delivery systems shrink warning windows. A posture that deliberately waits to absorb the first strike before replying [2] is the one most damaged when the interval to decide collapses.
• Cyber intrusion and spoofing: hacking or deceiving early-warning sensors and command networks raises the risk of retaliation against a false alarm — the gravest possible failure for an NFU state.
• AI-enabled surveillance and undersea detection: improved tracking erodes the concealment on which a survivable second strike depends.
• Counterforce temptation: as arsenals appear locatable, an adversary's incentive to strike first rises, weakening mutual restraint.

Why this bears particularly on India

• NFU makes survivability non-negotiable: India's stated position is that it will not use nuclear weapons first but will retaliate if attacked [2][4]; part of the force is therefore expected to be destroyed before it ever fires.
• The sea leg carries the pledge: INS Arighaat, the second Arihant-class submarine, was commissioned in August 2024; the government terms the sub-surface leg "the most potent part of the nuclear triad" and central to second-strike capability for a state professing no first use [3].
• Governance strain: release is reserved to the political leadership, with no delegation to the armed forces [1]. Shrinking timelines and hard-to-contact submarines create pressure toward pre-delegation.

Disruptive technologies thus attack survivability and decision time rather than warhead numbers. India's answer should be capability and clarity, not abandonment of restraint: hardened, redundant warning and command networks, assured communication with the sea-based deterrent, and continued reaffirmation of NFU on the record in Parliament [2][4] — which also sustains India's case that others adopt the same pledge [4]. Revisiting the doctrine's coverage while preserving its restraint best serves strategic stability.
