Global Security & Arms Control — NPT, CTBT, Peacekeeping & Disarmament

Why Global Security & Arms Control Matter

The architecture of global security rests on a framework of treaties, regimes, and institutions designed to prevent the use of weapons of mass destruction (WMDs), regulate conventional arms, and maintain international peace. For India -- a nuclear-armed state that is not a signatory to the NPT or CTBT -- navigating this landscape requires balancing national security imperatives with responsible global citizenship.

For UPSC, this topic spans GS-2 (International Relations, International Organisations) and is a favourite in both Prelims (treaty-specific factual questions) and Mains (essays on India's disarmament stance, UNSC reform).

UN Collective Security System

The United Nations Charter establishes a collective security system under which member states commit to resolving disputes peacefully and to acting collectively against threats to international peace.

Chapter VI vs Chapter VII

Chapter VII Mechanism

1. Article 39 -- The Security Council determines the existence of a threat to peace, breach of peace, or act of aggression
2. Article 40 -- Provisional measures (ceasefire calls) to prevent escalation
3. Article 41 -- Non-military measures: economic sanctions, severance of diplomatic relations, interruption of communications
4. Article 42 -- Military measures: if Article 41 measures prove inadequate, the UNSC may authorise air, sea, or land operations
5. Article 51 -- Preserves the inherent right of individual or collective self-defence until the Security Council takes action

The authorisation model was first used during the Korean War (1950) and revived with UNSC Resolution 678 (November 1990), which authorised "all necessary means" to ensure Iraq's withdrawal from Kuwait.

For Prelims: Chapter VII resolutions are binding on all UN member states. Chapter VI resolutions are recommendatory. The veto power of the P5 applies to both.

Nuclear Non-Proliferation Treaty (NPT)

The NPT, opened for signature in 1968 and entering into force in 1970, is the cornerstone of the global nuclear non-proliferation regime. It has near-universal membership, with 191 states parties as of 2026.

Three Pillars of the NPT

Five Recognised Nuclear-Weapon States (NWS)

The NPT recognises five states that tested nuclear weapons before 1 January 1967: the United States, Russia (successor to the USSR), United Kingdom, France, and China. These are also the five permanent members of the UNSC (P5).

Non-Signatories

Only four UN member states remain outside the NPT: India, Pakistan, Israel, and South Sudan. North Korea acceded to the NPT in 1985 but withdrew in 2003.

India's Position on the NPT

India has consistently refused to join the NPT, calling it a discriminatory treaty that creates a two-tier system of "nuclear haves" and "nuclear have-nots." India's key arguments:

• The NPT freezes the nuclear status quo as of 1967 and does not provide a pathway for states that tested later to be recognised as NWS
• The NWS have failed to fulfil their Article VI obligations on disarmament -- nuclear arsenals remain large decades after the treaty entered into force
• India seeks universal, non-discriminatory, and verifiable nuclear disarmament, not a regime that legitimises possession by five states while denying it to others
• Nuclear weapons are an integral part of India's national security and will remain so pending global disarmament

For Mains: India's NPT stance is not anti-non-proliferation but anti-discrimination. India has maintained a voluntary moratorium on nuclear testing since 1998 and has a clean non-proliferation record -- it has never exported nuclear weapons or technology to any state.

Comprehensive Nuclear-Test-Ban Treaty (CTBT)

The CTBT bans all nuclear explosions -- whether for military or peaceful purposes -- in all environments. It was adopted by the UN General Assembly in September 1996 but has not entered into force because it requires ratification by all 44 states listed in Annex 2 (states possessing nuclear reactors at the time).

CTBT Status

India's Position

India has not signed the CTBT. During negotiations in 1996, India objected on two grounds:

1. Entry-into-force provision -- The requirement that India must ratify for the treaty to enter into force was seen as an unprecedented coercive mechanism contrary to customary international law
2. No time-bound disarmament commitment -- The treaty bans testing but does not obligate NWS to eliminate nuclear weapons within a defined timeframe

India maintains a voluntary moratorium on nuclear testing since the Pokhran-II tests of May 1998, effectively observing the spirit of the CTBT without being bound by it.

Chemical Weapons Convention (CWC)

The CWC prohibits the development, production, stockpiling, and use of chemical weapons. It was opened for signature in January 1993 and entered into force on 29 April 1997.

India and the CWC

India was among the first signatories on 14 January 1993 and ratified the CWC on 2 September 1996. India declared possession of a limited quantity of chemical weapons and production facilities, which were completely destroyed under OPCW verification by March 2009 -- ahead of the international deadline. India established the National Authority for Chemical Weapons Convention (NACWC) in 2005 and enacted the Chemical Weapons Convention Act, 2000 for domestic implementation.

Biological Weapons Convention (BWC)

The BWC prohibits the development, production, and stockpiling of biological and toxin weapons. It was opened for signature in 1972 and entered into force in 1975.

The absence of a verification regime remains the BWC's most significant limitation. Efforts to negotiate a verification protocol have been stalled since the US rejected a draft protocol in 2001.

Multilateral Export Control Regimes

These regimes are voluntary groupings that regulate the transfer of sensitive materials and technologies to prevent WMD proliferation and destabilising accumulation of conventional arms.

India's Membership Status

Why NSG Membership Eludes India

The NSG operates by consensus, meaning any single member can block a new entrant. China has consistently opposed India's membership on the grounds that India is a non-signatory to the NPT. China insists on a "criteria-based approach" for admitting non-NPT states rather than a "country-specific" exception for India.

India received a special NSG waiver in 2008 (following the India-US Civil Nuclear Agreement) that allowed it to engage in civilian nuclear commerce despite not being an NPT signatory. However, full membership remains elusive.

For Prelims: India is a member of three of the four major export control regimes -- MTCR (2016), Wassenaar (2017), and Australia Group (2018). The NSG is the only one where India is not a member.

India's Nuclear Doctrine

India's nuclear doctrine was formally articulated on 4 January 2003 through a press release by the Cabinet Committee on Security (CCS). Its core tenets have remained unchanged.

Key Principles

Nuclear Command Authority (NCA)

The NCA comprises two bodies:

• Political Council -- Chaired by the Prime Minister; the sole body authorised to order a nuclear strike
• Executive Council -- Chaired by the National Security Advisor; provides inputs and executes directives of the Political Council

Nuclear Triad

India has developed a nuclear triad -- land-based missiles (Agni series), air-delivered weapons, and sea-based platforms (INS Arihant-class SSBNs) -- ensuring second-strike capability.

For Mains: India's NFU doctrine has faced periodic calls for revision. Proponents of revision argue that a preemptive strike capability against Pakistan's tactical nuclear weapons (Nasr missiles) may be necessary. Defenders of NFU contend that it provides strategic stability, enhances India's moral standing, and avoids destabilising first-strike postures.

UN Peacekeeping

UN peacekeeping operations deploy military, police, and civilian personnel to help countries transition from conflict to peace. They operate under Chapter VI (consent-based) or Chapter VII (enforcement) mandates.

India's Peacekeeping Contribution

India is among the largest contributors of uniformed personnel to UN peacekeeping, with a legacy stretching back to the very first UN peacekeeping mission.

UNMOGIP

The United Nations Military Observer Group in India and Pakistan (UNMOGIP), established in January 1949, supervises the ceasefire along the Line of Control in Jammu and Kashmir. It is one of the oldest UN missions still in operation.

• India's position: the UNMOGIP mandate lapsed after the 1972 Simla Agreement, which established the LoC and stipulated bilateral resolution of the Kashmir dispute
• Pakistan's position: UNMOGIP remains relevant and its mandate continues
• The mission continues to operate with a small complement of military observers, though India does not permit UNMOGIP operations on its side of the LoC

India's Bid for a Permanent UNSC Seat

India has long advocated for reform of the UN Security Council to reflect contemporary geopolitical realities rather than the post-World War II power structure.

G4 Nations

India is part of the G4 grouping -- comprising Brazil, Germany, India, and Japan -- which supports each other's bids for permanent seats on an expanded UNSC.

Support and Opposition

India's Case

• Population: India represents roughly one-sixth of humanity
• Economy: 5th largest economy by nominal GDP
• Peacekeeping: Among the largest troop contributors to UN operations
• Democratic credentials: World's largest democracy
• Financial contribution: A growing contributor to the UN regular and peacekeeping budgets

For Mains: UNSC reform requires an amendment to the UN Charter (Article 108), which needs a two-thirds majority in the General Assembly and ratification by two-thirds of UN members, including all five current permanent members. This gives each P5 member an effective veto over reform -- making expansion politically difficult despite broad support.

Arms Trade Treaty (ATT)

The ATT, adopted by the UN General Assembly in April 2013 and entering into force in December 2014, regulates the international trade in conventional arms -- from small arms to battle tanks, combat aircraft, and warships.

India abstained on the grounds that the treaty does not adequately address the concerns of importing states, focuses disproportionately on exporters' obligations, and does not sufficiently address illicit trafficking and diversion -- India's primary concerns.

Small Arms and Light Weapons (SALW)

The UN Programme of Action (UNPoA) on small arms and light weapons, adopted in 2001, is the primary international framework addressing illicit SALW trafficking. It requires states to improve national regulations, strengthen stockpile management, ensure proper marking of weapons, and enhance cooperation in weapons tracing.

India faces SALW proliferation challenges particularly in:

• Northeast India -- Insurgent groups procure weapons from Myanmar and through maritime routes
• J&K -- Cross-border smuggling of arms from Pakistan
• Naxal-affected areas -- Maoist groups manufacture improvised weapons and procure small arms through illicit channels

Nuclear Security Summits

Four Nuclear Security Summits were held between 2010 and 2016, initiated by US President Barack Obama to secure vulnerable nuclear materials worldwide.

India participated in all four summits and established the GCNEP as a state-of-the-art facility for international cooperation on nuclear safety, with MOUs signed with France, Russia, the US, and the IAEA.

Key Comparison Table: Major Arms Control Treaties

Key Terms for Prelims

Recent Developments (2024–2026)

Russia-Ukraine War — Arms Control Implications (2024–2025)

The ongoing Russia-Ukraine war has severely damaged the global arms control architecture. Russia suspended the New START Treaty (the last major US-Russia nuclear arms control agreement) in February 2023 and withdrew from it in November 2023, ending decades of bilateral nuclear arms control. This means there are no binding limits on US or Russian nuclear arsenals for the first time since 1972. The P5 (five Nuclear Weapons States under the NPT) failed to issue a joint statement at the NPT Preparatory Committee (PrepCom) meetings in 2024, reflecting deep divisions.

India maintained its consistent position: global disarmament must be universal, non-discriminatory, and verifiable — targeting a NWFW (nuclear weapons-free world) through a time-bound, phased framework. India supported calls for US-Russia resumption of strategic stability dialogue.

UPSC angle: Russia's START treaty withdrawal (2023), the collapse of bilateral arms control, and India's advocacy for universal disarmament are important for GS-II global security questions.

India's Missile Technology and Export Control Regimes (2024)

India joined the Wassenaar Arrangement (2017) and MTCR (2016) as a member, and the Australia Group (2018). India's membership in these four export control regimes (NSG, MTCR, Wassenaar, Australia Group — all except full NSG membership due to China's veto) strengthens its case for responsible nuclear commerce. In 2024, India's defence exports reached a record USD 21,083 crore (approximately USD 2.5 billion) — the highest ever — with exports to 85 countries, including BrahMos missile systems to the Philippines.

UPSC angle: India's export control regime memberships (MTCR: 2016, Wassenaar: 2017, Australia Group: 2018, NSG: pending) and India's defence export achievements (USD 2.5 billion FY 2024–25) are important Prelims facts.

India-Pakistan Nuclear Risks — Post-Sindoor Analysis (May 2025)

Operation Sindoor (May 2025) and the India-Pakistan military confrontation raised unprecedented concerns about nuclear escalation risks between the two nuclear-armed states. Both countries possess nuclear weapons (India: estimated 160+ warheads; Pakistan: estimated 170+), and both have delivery systems covering each other's major cities. The 4-day conflict ended with a US-mediated ceasefire on 10 May 2025, with the nuclear dimension underscoring the urgent need for crisis communication mechanisms.

The episode renewed calls for India and Pakistan to establish a bilateral nuclear risk reduction centre (NRRC) and for formalising communication channels between the two Directors-General of Military Operations (DGMOs), beyond the existing hotline that was reportedly used during the ceasefire negotiations.

UPSC angle: India-Pakistan nuclear dynamics (both non-NPT nuclear states, estimated arsenal sizes), risks of escalation in sub-conventional conflicts, and the absence of formal crisis management mechanisms (unlike US-Russia "hotline") are critical Mains analytical themes.

AI and Autonomous Weapons — UN Discussions (2024)

The UN General Assembly adopted a consensus resolution in 2024 calling for international norms on Lethal Autonomous Weapons Systems (LAWS) — "killer robots" that can select and engage targets without human control. India participated in the Convention on Certain Conventional Weapons (CCW) discussions, calling for meaningful human control over life-and-death decisions and opposing fully autonomous weapons. India's position: technology should augment human decision-making in warfare, not replace it.

UPSC angle: LAWS (Lethal Autonomous Weapons Systems), the CCW framework, and India's support for "meaningful human control" are emerging topics at the intersection of GS-II (arms control) and GS-III (technology and security).

Exam Strategy
