Background and Context

  • START‑I (1991‑1994): First bilateral treaty to reduce strategic arms after the Cold War.
  • SORT (2002): Replaced START‑I but lacked verification mechanisms.
  • New START (2010‑2021): Introduced robust verification, data exchanges, and on‑site inspections, becoming the cornerstone of US‑Russia nuclear stability.
  • Geopolitical Climate: Tensions over Ukraine, missile‑defence systems, and development of hypersonic weapons strained the treaty, leading to Russia’s suspension and eventual lapse.

Significance for India / Governance / Policy

  • Strategic Uncertainty: With no bilateral limits, the risk of a renewed arms race could affect regional security dynamics, compelling India to reassess its nuclear doctrine and force posture.
  • Arms Control Diplomacy: The lapse hampers efforts to bring other nuclear powers, especially China, into a broader arms‑control framework, limiting India's ability to advocate for multilateral disarmament.
  • Non‑Proliferation Regime: Undermines the credibility of the NPT and related treaties, potentially influencing India’s stance in international forums on nuclear disarmament and peaceful nuclear energy.
  • Policy Implications: May trigger discussions on enhancing strategic stability dialogues, confidence‑building measures, and modernising India's own verification and monitoring capabilities.

Related Constitutional / Legal Provisions

  • Article 51 (a) & (b) of the Indian Constitution: Duty to promote international peace, security, and maintain just and honorable relations with other nations.
  • United Nations Charter – Article 2(4): Prohibition of the threat or use of force, relevant to nuclear deterrence policies.

  • Treaty on the Prohibition of Nuclear Weapons (TPNW), 2017 – India has not joined.

Global Initiatives Related to Nuclear Weapons Management

  • NPT (1968): Prevents spread, promotes disarmament, and peaceful use of nuclear energy.
