Why this chapter matters for UPSC: Peace theory underpins every international relations question in GS2 — from UN peacekeeping to nuclear disarmament, arms control treaties to India's foreign policy doctrine. The distinction between negative and positive peace, just war criteria, and peace-building vs peacekeeping concepts are tested in both Prelims and Mains essays.

Contemporary hook: The Russia-Ukraine war (2022-present), Israel-Hamas conflict (2023-present), and India's consistent stand on dialogue-based resolution at the UN General Assembly reflect live debates on the nature of peace, the limits of just war theory, and the relevance of non-violence in contemporary world politics.


PART 1 — Quick Reference Tables

Negative Peace vs Positive Peace

Dimension Negative Peace Positive Peace
Definition Absence of direct armed conflict/war Absence of structural violence + presence of justice, equality, cooperation
Focus Preventing war Building conditions that make war unnecessary
Associated with Ceasefires, deterrence, arms control Development, human rights, democracy, economic equality
Theorist Johan Galtung (coined distinction, 1964) Johan Galtung; also Gandhi's sarvodaya
Critique Peace without justice is "cold peace" Hard to achieve; depends on political will
Example 1947–1991 Cold War (no world war, but proxy wars, arms race) Scandinavian welfare states — low violence, high equality

Just War Theory — Criteria

Criterion Latin Term Meaning
Just cause Jus ad bellum War only for self-defence or to protect innocents
Right intention Not for conquest, revenge, or economic gain
Proper authority Declared by legitimate government
Last resort All peaceful means exhausted first
Probability of success War should not be futile
Proportionality Harm caused must not exceed good achieved
Discrimination (in war) Jus in bello Distinguish combatants from civilians; no targeting civilians
Proportionality (in war) Jus in bello No excessive force relative to military objective

Key Arms Control Treaties

Treaty Year Parties What It Does
NPT (Non-Proliferation Treaty) 1968 191 states Prevents spread of nuclear weapons; recognises 5 NWS (US, Russia, UK, France, China)
CTBT (Comprehensive Test Ban Treaty) 1996 (not in force) 177 signed, not ratified by US, China, India Bans all nuclear test explosions
START (Strategic Arms Reduction Treaty) 1991, New START 2010 US–Russia Limits deployed nuclear warheads
CWC (Chemical Weapons Convention) 1993 193 parties Bans production, stockpiling, use of chemical weapons
BWC (Biological Weapons Convention) 1972 183 parties Bans biological weapons
Ottawa Treaty (Anti-Personnel Mines) 1997 164 parties Bans landmines
TPNW (Treaty on Prohibition of Nuclear Weapons) 2017 92 signed Complete nuclear weapon ban (NWS oppose it)

India's Arms Control Positions

Treaty/Issue India's Stand
NPT Not a signatory — considers NPT discriminatory (only 5 states allowed nuclear weapons)
CTBT Not ratified — willing to join only after US ratifies
TPNW Not a signatory — supports global nuclear disarmament but on non-discriminatory basis
Biological/Chemical weapons Party to BWC and CWC
Conventional arms Advocates against small arms proliferation

PART 2 — Detailed Notes

What is Peace?

Key Term

Peace: More than the mere absence of war. Peace involves the absence of violence in all its forms — physical, structural, and cultural — and the presence of conditions that allow all people to live with dignity, freedom, and justice.

The common-sense understanding of peace as "no war" is what Johan Galtung (Norwegian peace theorist) called negative peace. True or positive peace requires:

  • Justice and equality (no structural violence — poverty, discrimination)
  • Human rights and dignity
  • Cooperation between peoples and nations
  • Environmental sustainability (environmental violence as a threat to peace)

Violence is not only physical:

  • Direct violence: War, terrorism, murder
  • Structural violence: Poverty, discrimination, deprivation built into institutions (a society where people die of preventable diseases due to inequality)
  • Cultural violence: Norms, ideologies that justify direct and structural violence (racism, casteism, religious extremism)
Explainer

Galtung's peace research: Johan Galtung founded the Journal of Peace Research (1964) and the Peace Research Institute Oslo (PRIO). His framework expanded "peace" from a geopolitical concept to a social justice concept — relevant for understanding why UPSC's GS4 (ethics) includes "peace" alongside justice and fairness.

Gandhi and Non-Violence

Key Term

Ahimsa (Non-violence): Gandhi's foundational ethical principle — the refusal to harm any living being in thought, word, or deed. Applied to politics, it means confronting injustice through non-violent resistance (Satyagraha) rather than violent revolution.

Satyagraha: "Truth-force" or "soul-force" — Gandhi's method of non-violent resistance. Not passive acceptance but active, disciplined confrontation with injustice while refusing to dehumanise the opponent.

Gandhi's Peace Philosophy:

  • Means and ends are inseparable: Violent means cannot produce a peaceful end. A free India achieved through violence would carry violence in its foundations.
  • Individual transformation: Peace begins with inner transformation — overcoming greed, anger, fear. Social peace requires personal non-violence.
  • Sarvodaya: "Welfare of all" — peace cannot be peace for one nation/class if achieved at the expense of others.
  • Constructive programme: Gandhi believed peace requires building just institutions, not just opposing unjust ones.

Gandhi's influence globally:

  • Martin Luther King Jr. (US Civil Rights Movement) — explicitly modelled his strategy on Gandhian non-violence
  • Nelson Mandela (anti-apartheid, South Africa) — drew on Gandhi's South Africa period
  • Aung San Suu Kyi (Myanmar) — cited Gandhian non-violence (though subsequently contested)
UPSC Connect

UPSC Essay/Mains: Gandhi's non-violence is frequently an essay topic ("Non-violence is not just a political strategy but a way of life") and appears in GS2 (India's foreign policy) and GS4 (ethics — relevant philosophers). Also note: International Day of Non-Violence = October 2 (Gandhi's birthday), declared by UN General Assembly 2007.

Just War Theory

The just war tradition is centuries old (Augustine, Aquinas, Grotius) but remains the primary moral framework for evaluating the legitimacy of armed conflict.

Two parts:

  1. Jus ad bellum (justice in going to war) — criteria for when it is permissible to start a war
  2. Jus in bello (justice in the conduct of war) — rules governing behaviour once war begins (forms the basis of international humanitarian law/Geneva Conventions)

Modern just war debates:

  • Self-defence: Article 51 of the UN Charter permits states to use force in self-defence — the one universally accepted "just cause" in international law.
  • Humanitarian intervention: Is it just to go to war to protect civilians in another country from genocide? NATO's Kosovo intervention (1999), Libya intervention (2011) — debated cases.
  • Pre-emptive vs preventive war: Pre-emptive (attack imminent) may be justified; preventive (attack not imminent but feared) is much harder to justify under just war criteria. US Iraq War 2003 used "preventive" logic and remains highly contested.
  • Terrorism and just war: Non-state actors (terrorists) don't follow jus in bello; does this change the rules for states fighting them?
Explainer

Responsibility to Protect (R2P): A 2005 UN World Summit principle that states have a responsibility to protect their populations from genocide, war crimes, ethnic cleansing, and crimes against humanity — and if they fail, the international community has the right (and duty) to intervene. R2P is the most recent evolution of just war thinking in international law. India's position: supports R2P in principle but opposes its military implementation without UNSC authorisation (concerns about sovereignty).

Nuclear Weapons and Peace

Key Term

Nuclear Deterrence: The theory that the threat of nuclear retaliation prevents nuclear attack — "Mutually Assured Destruction" (MAD). If both sides know nuclear war means mutual annihilation, neither will strike first.

Arguments for deterrence:

  • No world war since 1945 — the "Long Peace" is partly attributed to nuclear deterrence
  • Rationalist model: Leaders are deterred by the catastrophic consequences
  • Stability: States with nuclear weapons rarely fight direct wars with each other

Arguments against nuclear deterrence:

  • Near misses: Cuban Missile Crisis (1962), Able Archer exercise (1983), Stanislav Petrov incident (1983) — deterrence nearly failed multiple times
  • Irrational actors: Deterrence assumes rational decision-makers — not guaranteed
  • Proliferation risk: More nuclear states = more risk (Pakistan-India, North Korea)
  • Accidental launch: Technical failures, miscommunication
  • Humanitarian catastrophe: No "winnable" nuclear war; even a limited nuclear exchange causes nuclear winter affecting global food supply

India's Nuclear Doctrine:

  • No First Use (NFU): India will not be the first to use nuclear weapons
  • Massive retaliation: In case of nuclear attack on India, response will be punishing
  • Civilian control: Nuclear command authority rests with the Political Council (PM at head)
  • Non-weaponisation against non-nuclear states: Will not threaten non-nuclear states
UPSC Connect

UPSC Prelims: India is not a member of NPT but has safeguard agreements with IAEA (for civilian nuclear facilities). The India-US Civil Nuclear Deal (2008) allowed India access to nuclear technology despite not being in NPT. NSG (Nuclear Suppliers Group) membership — India seeks it, China blocks it.

United Nations and Peace

UN's role in maintaining peace:

  1. UN Security Council (UNSC):

    • 15 members: 5 permanent (P5: US, Russia, UK, France, China) + 10 non-permanent (2-year terms)
    • Primary responsibility for international peace and security
    • Can impose sanctions, authorise force, refer cases to ICC
  2. UN General Assembly (UNGA):

    • All 193 member states; one country, one vote
    • Makes recommendations but not binding decisions on peace and security
    • Can act when UNSC is deadlocked (Uniting for Peace Resolution)
  3. UN Peacekeeping:

    • Blue Helmets deployed to conflict zones with consent of parties
    • Mandate: Monitor ceasefires, protect civilians, support elections, help post-conflict reconstruction
    • India is among the largest troop-contributing countries to UN peacekeeping missions (has contributed over 2.5 lakh troops since 1950, with 180+ soldiers killed in service)
    • Current missions: India deploys troops to multiple active missions (South Sudan, Congo, Lebanon, etc.)
UPSC Connect

UPSC: India's record in UN peacekeeping is a recurring theme. General Prem Chand commanded first UN force (Congo, 1960–61). India's female peacekeepers (all-female unit in Liberia, 2007) are celebrated. India advocates for UNSC reform — permanent membership for itself, but P5 veto blocks expansion. The UNSC veto reform debate appears in Mains.

UN peace-building vs peacekeeping:

Dimension Peacekeeping Peace-building
Focus Stop ongoing violence Prevent recurrence of conflict
Phase During/immediately after conflict Post-conflict
Activities Military monitoring, civilian protection Institution building, elections, reconciliation, economic recovery
UN body DPKO (Dept of Peace Operations) UN Peacebuilding Commission (PBC, est. 2005)

Panchsheel and India's Peace Doctrine

Key Term

Panchsheel (Five Principles of Peaceful Coexistence):

  1. Mutual respect for sovereignty and territorial integrity
  2. Mutual non-aggression
  3. Non-interference in each other's internal affairs
  4. Equality and mutual benefit
  5. Peaceful coexistence

Signed between India and China as part of the 1954 Tibet trade agreement; subsequently adopted as a foundational principle of the Non-Aligned Movement and India's foreign policy.

Limitations of Panchsheel in practice:

  • China violated Panchsheel by attacking India in 1962 — a major diplomatic setback
  • Critics argue non-interference can shield authoritarian regimes from accountability
  • Tension between Panchsheel (sovereignty) and R2P (humanitarian intervention) in modern discourse

India's broader peace doctrine:

  • Non-Aligned Movement (NAM): Founded 1955, Bandung Conference — India under Nehru was a founding force
  • Strategic Autonomy: India refuses to join military blocs; preserves independent foreign policy
  • "Vasudhaiva Kutumbakam" (World is One Family): Cited by India at G20 (2023 Presidency) as its civilisational approach to peace

PART 3 — Frameworks & Analysis

Peace — Multiple Dimensions for Mains

Peace as a spectrum:

  • No war → Negative peace → Positive peace → Just peace
  • Gandhi would argue even "negative peace" under oppression is not true peace

Causes of war (three levels analysis):

  • Individual level: Human nature (aggression, greed) — Hobbes' view
  • State level: Internal politics — democracies more peaceful? (Democratic Peace Theory — democracies rarely fight each other)
  • International level: Anarchy — no world government to enforce peace

Democratic Peace Theory:

  • Immanuel Kant's "Perpetual Peace" (1795) — republics won't fight each other
  • Empirical finding: Democracies have almost never fought other democracies (though they fight non-democracies)
  • Explanation: Shared values, public accountability, economic interdependence
  • Critique: Doesn't prevent democracies from fighting authoritarian states; recent democratic backsliding complicates the theory

India's Approach to Peace — Summary Framework

India's peace philosophy integrates:

  1. Gandh'is ahimsa — non-violence as first principle
  2. Panchsheel — sovereignty-based peaceful coexistence
  3. NAM — strategic autonomy, oppose military blocs
  4. UN multilateralism — reform the system from within
  5. Nuclear doctrine — minimum credible deterrence + NFU

Exam Strategy

Prelims traps:

  • Panchsheel was signed in 1954 (India-China Tibet trade agreement) — not 1955 (which was Bandung Conference)
  • NPT recognises 5 nuclear weapon states — US, Russia, UK, France, China. India, Pakistan, Israel, North Korea are outside NPT
  • CTBT is not in force — US, China, India, Pakistan, Israel have not ratified it
  • UN peacekeeping — India is a top troop contributor, not a P5 member of UNSC
  • International Day of Non-Violence = October 2 (Gandhi Jayanti)

Mains frameworks:

  • On peace and conflict: Negative peace vs positive peace → structural violence → Galtung framework → India's approach (Panchsheel, NAM, UN) → contemporary challenges
  • On nuclear disarmament: Deterrence theory → near misses → humanitarian costs → NPT discrimination → India's stand → way forward (TPNW, CTBT ratification)
  • On UN reform: UNSC veto → India's case for permanent seat → P4+1 coalition → reform proposals → prospects
