BharatNotes 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
| Feature | Chapter VI — Pacific Settlement | Chapter VII — Enforcement Action |
|---|---|---|
| Nature | Non-binding recommendations | Binding decisions |
| Tools | Negotiation, mediation, arbitration, judicial settlement | Sanctions, blockades, military action |
| Key articles | Articles 33--38 | Articles 39--51 |
| Trigger | Dispute likely to endanger peace | Threat to the peace, breach of the peace, or act of aggression |
| Force | No use of force authorised | Military force authorised under Articles 42--43 |
Chapter VII Mechanism
- Article 39 -- The Security Council determines the existence of a threat to peace, breach of peace, or act of aggression
- Article 40 -- Provisional measures (ceasefire calls) to prevent escalation
- Article 41 -- Non-military measures: economic sanctions, severance of diplomatic relations, interruption of communications
- Article 42 -- Military measures: if Article 41 measures prove inadequate, the UNSC may authorise air, sea, or land operations
- 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
| Pillar | Obligation | Key Article |
|---|---|---|
| Non-Proliferation | Nuclear-weapon states (NWS) shall not transfer nuclear weapons to non-nuclear-weapon states (NNWS); NNWS shall not acquire them | Articles I & II |
| Disarmament | All parties, especially NWS, shall pursue negotiations in good faith towards complete nuclear disarmament | Article VI |
| Peaceful Uses | All parties have the inalienable right to develop nuclear energy for peaceful purposes | Article IV |
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
| Parameter | Detail |
|---|---|
| Opened for signature | September 1996 |
| Signatories | 187 states |
| Ratifications | 178 states |
| Entry into force | Pending -- requires all 44 Annex 2 states |
| Annex 2 holdouts | India, Pakistan, North Korea (not signed); USA, China, Egypt, Iran, Israel (signed but not ratified) |
India's Position
India has not signed the CTBT. During negotiations in 1996, India objected on two grounds:
- 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
- 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.
| Parameter | Detail |
|---|---|
| States Parties | 193 (near-universal) |
| Non-parties | Egypt, North Korea, South Sudan (neither signed nor ratified); Israel (signed, not ratified) |
| Implementing body | Organisation for the Prohibition of Chemical Weapons (OPCW), headquartered in The Hague |
| Verification | Extensive on-site inspections by OPCW |
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.
| Parameter | Detail |
|---|---|
| States Parties | 187 |
| Key weakness | No formal verification mechanism (unlike the CWC) |
| India's status | Signed and ratified in 1974 |
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
| Regime | Focus | Founded | Members | India's Status |
|---|---|---|---|---|
| MTCR (Missile Technology Control Regime) | Missiles capable of delivering WMDs (range 300+ km, payload 500+ kg) | 1987 | 35 | Member since June 2016 |
| Wassenaar Arrangement | Conventional arms and dual-use technologies | 1996 | 42 | Member since December 2017 |
| Australia Group | Chemical and biological weapons precursors | 1985 | 43 | Member since January 2018 |
| NSG (Nuclear Suppliers Group) | Nuclear materials, equipment, technology | 1974 | 48 | Not a member -- bid blocked by China |
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
| Principle | Detail |
|---|---|
| No First Use (NFU) | India will not use nuclear weapons first; they will be used only in retaliation against a nuclear attack on Indian territory or Indian forces anywhere |
| Credible Minimum Deterrence | India will maintain a nuclear arsenal sufficient to inflict unacceptable damage in retaliation but will not engage in an arms race |
| Massive Retaliation | Nuclear retaliation to a first strike will be massive and designed to cause unacceptable damage |
| Non-use against NNWS | India will not use nuclear weapons against non-nuclear-weapon states |
| Chemical/Biological exception | India may use nuclear weapons in response to a major attack on India using biological or chemical weapons |
| Civilian control | The authority to order a nuclear strike rests solely with the civilian political leadership through the Nuclear Command Authority (NCA) |
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.
| Parameter | Detail |
|---|---|
| Total missions participated | Over 49 missions since 1950 |
| Total personnel deployed historically | Over 200,000 troops and significant police personnel |
| Current deployment | Approximately 5,900--6,000 personnel across 12 missions (2024) |
| Sacrifices | 179 Indian peacekeepers have been killed in service of international peace |
| Notable early missions | Korea (1950s), Suez (UNEF I, 1956), Congo (ONUC, 1960) |
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
| Category | Details |
|---|---|
| P5 supporters | France, Russia, United Kingdom, and the United States have endorsed India's candidacy |
| China's position | Has endorsed Indian candidacy conditionally -- India must revoke support for Japan's bid (given China-Japan tensions) |
| Opposition bloc | Uniting for Consensus (UfC) group, led by Pakistan, Italy, South Korea, Argentina -- opposes expansion of permanent seats |
| G4 compromise | In 2017, G4 nations offered to temporarily forgo veto power if granted permanent seats |
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.
| Parameter | Detail |
|---|---|
| States Parties | 116 (as of 2024) |
| Signatories | 130 |
| India's status | Abstained during the vote; has not signed or ratified |
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.
| Summit | Year | Location | Key Outcome |
|---|---|---|---|
| NSS I | 2010 | Washington, DC | Communique to secure all vulnerable nuclear material within four years; India announced a Global Centre for Nuclear Energy Partnership (GCNEP) |
| NSS II | 2012 | Seoul, South Korea | Focus on nuclear terrorism and radiological security |
| NSS III | 2014 | The Hague, Netherlands | India joined INFCIRC/869 -- strengthening nuclear security implementation through the IAEA |
| NSS IV | 2016 | Washington, DC | Five action plans for international organisations to continue summit work |
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
| Treaty/Regime | Opened | In Force | India's Status | Key Point |
|---|---|---|---|---|
| NPT | 1968 | 1970 | Not signed | Calls it discriminatory |
| CTBT | 1996 | Not yet | Not signed | Voluntary testing moratorium since 1998 |
| CWC | 1993 | 1997 | Ratified (1996) | Destroyed all stocks by 2009 |
| BWC | 1972 | 1975 | Ratified (1974) | No verification mechanism |
| ATT | 2013 | 2014 | Abstained | Concerns about importer interests |
| MTCR | 1987 | -- | Member (2016) | Voluntary regime |
| NSG | 1974 | -- | Not a member | Waiver in 2008; blocked by China |
| Wassenaar | 1996 | -- | Member (2017) | Dual-use tech controls |
| Australia Group | 1985 | -- | Member (2018) | Chemical/bio precursors |

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 its participation in New START on 21 February 2023 (citing Western support for Ukraine). The treaty itself formally expired on 5 February 2026 — its maximum extension date under treaty terms — without renewal or replacement. On 4 February 2026, Russia's Foreign Ministry declared the treaty's obligations no longer binding. 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 2023, 2024, and 2025, 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: New START timeline — Russia suspended February 2023; treaty expired 5 February 2026 (not renewed); no binding US-Russia nuclear arsenal limits for first time since 1972. 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 FY 2024-25, India's defence exports reached a record Rs 23,622 crore (approximately USD 2.76 billion) — a 12.04% rise over FY 2023-24's Rs 21,083 crore (USD 2.5 billion) — with exports to ~80 countries, including BrahMos missile systems to the Philippines. The government's target is Rs 50,000 crore by 2029.
UPSC angle: India's export control regime memberships (MTCR: 2016, Wassenaar: 2017, Australia Group: 2018, NSG: pending) and India's defence export achievements (Rs 23,622 crore / ~USD 2.76 billion, FY 2024-25, PIB — new record, 12.04% growth) are important Prelims facts.
NPT Review Conference 2026 — Underway (April–May 2026)
The 11th NPT Review Conference is being held 27 April – 22 May 2026 at UN Headquarters, New York (President: Ambassador Do Hung Viet of Vietnam). As of 28 May 2026, the conference is in its final week. The third and final Preparatory Committee (PrepCom) meeting was held 28 April – 9 May 2025 (Chair: Ambassador Harold Agyeman of Ghana). Critically, none of the three PrepCom sessions (2023, 2024, 2025) agreed on substantive outcomes — reflecting deep divisions between nuclear-weapon states (NWS) and non-nuclear-weapon states (NNWS), particularly over Russia's suspension and expiry of New START (expired 5 February 2026) and the P5's failure to fulfil Article VI disarmament obligations. India (non-NPT) participates as an observer. The expiry of New START days before the RevCon began (5 February 2026) created an unprecedented backdrop — no binding US-Russia arms control treaty in force for the first time in 54 years.
UPSC angle: 11th NPT Review Conference (27 April – 22 May 2026, New York) — currently underway; President Ambassador Do Hung Viet (Vietnam); third PrepCom (April–May 2025) failed to agree on outcomes; New START expiry (5 February 2026) as major backdrop; India's non-NPT position and advocacy for universal, non-discriminatory, verifiable disarmament. The NPT regime deadlock is a Mains 2026 analytical theme.
NSG — South Africa Hosts 50th Anniversary Plenary (2025)
The Nuclear Suppliers Group's 2025 Plenary Week was hosted by South Africa (current NSG Chair), marking the Group's 50th anniversary. The focus was on modernising NSG guidelines for emerging nuclear technologies, including small modular reactors (SMRs) and advanced nuclear fuel technologies. India's membership bid remains blocked by China, which continues to insist on a "criteria-based approach" (requiring NPT signature) rather than a country-specific exception. All other NSG members support India's membership. Pakistan simultaneously seeks membership, which India and most NSG members oppose.
UPSC angle: NSG 50th anniversary 2025 (South Africa chair); India's bid continues to be blocked by China (NPT pre-condition); all other members support India. India received the original NSG waiver in 2008 (September 6, Vienna) — distinguish waiver (allows civilian nuclear commerce) from full membership.
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.
Pakistan's nuclear signalling: On 9 May 2025, Pakistan's National Command Authority (NCA) — its nuclear command body — reportedly convened, which analysts characterised as "soft nuclear signalling." Pakistan also fired four missiles towards New Delhi on the night of 9–10 May 2025, all intercepted by India's air defence. The episode is significant as it demonstrated the escalation ladder risks in sub-conventional conflicts between nuclear-armed states.
India's doctrinal implication: Operation Sindoor challenged Pakistan's strategy of using its nuclear umbrella to deter Indian conventional retaliation for cross-border terrorism. India's willingness to conduct precision strikes despite Pakistan's nuclear posture signals that India has carved out space for military action below the nuclear threshold — a significant shift in nuclear deterrence dynamics in South Asia.
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.
UPSC angle: India-Pakistan nuclear dynamics (both non-NPT nuclear states; India: ~180 warheads (SIPRI Yearbook 2025, January 2025 estimate), Pakistan: ~170 warheads (SIPRI 2025) — India now marginally leads), Pakistan's NCA convening (9 May 2025), Operation Sindoor and "sub-threshold" military action, nuclear blackmail strategy challenged, and the absence of formal crisis management mechanisms (unlike US-Russia) — are critical Mains analytical themes for Mains 2026.
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
- Prelims: Expect factual questions on treaty years, India's membership status in export control regimes, CTBT Annex 2 requirements, and CWC/BWC differences. The comparison table above is high-yield.
- Mains: Be prepared to write balanced essays on India's NPT stance, the NFU debate, UNSC reform challenges, and the effectiveness of multilateral arms control in the 21st century. Always link to India's strategic autonomy doctrine.
- Essay: Topics like "Is nuclear disarmament achievable?" or "Can the UN collective security system deliver in a multipolar world?" draw directly from this chapter.
Key Terms
Wassenaar Arrangement
- Definition: The Wassenaar Arrangement is a voluntary, multilateral export control regime (established 1996, Secretariat in Vienna) through which participating states coordinate national controls on the export of conventional arms and dual-use goods and technologies to prevent destabilising accumulations and diversion to actors of concern.
- Context: It was the first global multilateral arrangement covering both conventional weapons and sensitive dual-use items, succeeding the Cold War-era Coordinating Committee for Multilateral Export Controls (CoCom), which had targeted the Soviet bloc. The agreement to set it up was reached in December 1995 at Wassenaar, Netherlands, and it became operational with the adoption of its Initial Elements at the July 1996 Plenary. It maintains control lists that members apply through their own national laws, with all decisions taken by consensus. India joined as the 42nd participating state on 8 December 2017.
- UPSC Relevance: This is a foundational concept for GS2 (international relations, India and global groupings) and frequently tested in Prelims through the family of multilateral export control regimes (MECRs) — Wassenaar Arrangement, MTCR, Australia Group and Nuclear Suppliers Group. Aspirants must distinguish what each regime covers (Wassenaar: conventional arms + dual-use tech; MTCR: missiles; Australia Group: chemical/biological; NSG: nuclear) and recall India's membership status — India is a member of three of the four, with NSG full membership still pending. Mains GS2 angles include how these memberships strengthen India's non-proliferation credentials and improve access to high technology.
