Key Terms in International Relations
This chapter is the glossary-foundation of the whole subject —read every term before proceeding. Try to retain the technical terms exactly.
Basic Terms of International Relations
| Term | Meaning |
| Anti-ballistic Missile | A two-component system — a radar + an interceptor missile — that defends a designated target against an incoming enemy missile. |
| Accidental War | Two senses: (i) war from a technical malfunction/mishap (unintentional); (ii) from misperception — a state misreads a situation and responds with violence. |
| Action–Reaction | From conflict analysis & game theory. Lewis Fry Richardson (Richardson process) modelled the arms race: B arms → A feels threatened & arms → B’s safety margin shrinks → B arms further. An action breeds a reaction (arms spiral). |
| Actor | Any entity playing an identifiable role / stakeholder — persons, organisations, states, institutions. A deliberately broad term. |
| Adjudication | Settling international disputes by referring them to a court of law. Post-WWI the League set up the Permanent Court of International Justice, succeeded by the ICJ in 1945. |
| Administered Territory | Advocated by Jan Smuts & George Louis Beer under Article XXII, League Covenant to administer ex-German/Turkish colonies — no direct annexation; ‘responsible’ states in ‘sacred trust’; run by the Permanent Mandates Commission (per Northedge, the first experiment in international control of dependent territories). |
| AIC (Advanced Industrial Countries) | Term from the Brandt Report, 1980 — N. America, W. Europe, Japan, Australia; the UN uses it for all developed countries. |
| Alliance | Two+ actors formally sign to cooperate on security — usually defence pacts operating in war. Most visible in the Cold War; per Christensen & Snyder, strong alliances are harder in a multipolar world. |
| Arbitration | Parties submit their dispute to a third party, whose decision is binding. |
| Arms Control | Restraint in acquiring/deploying/using military capabilities; rests on deterrence. Differs from disarmament (a weapons-free world) — arms controllers work within the existing structure. |
| Armistice | A bilateral, temporary suspension of hostilities to seek peace; maintains status quo. E.g., Arab–Israel armistice 1949–1978. |
| Asian Tigers | High-growth East-Asian economies. Standard ‘Four Asian Tigers’ = Hong Kong, Singapore, South Korea, Taiwan. Tiger Cubs = Malaysia, Thailand, Indonesia; Asian Dragons = Hong Kong & China. |
| Asylum | Refuge; a quasi-legal process. Per Article 14, UDHR 1948, the right of asylum vests in the state, not the individual. |
| Autonomy | Self-government. Origin traced to the Treaty of Westphalia, 1648, which also introduced anarchy among states. |
| Anarchy | Greek: ‘without a ruler’. In IR, a system where no state has absolute control. Thomas Hobbes first described IR as anarchical; central to realist theory. |
| Appeasement | Belief that meeting an aggressor’s demands will prevent war. |
| Balkanization | Late-19th-c. term (Balkan = Turkish for ‘forested mountains’) for fragmentation of a region into mutually hostile power-centres — used of ex-Ottoman states (Albania, Bulgaria, Greece, Romania, Yugoslavia). |
| Bases | Points of military supply & troop concentration; in the Cold War, US & USSR placed them in allies’ territory. |
| Balance of Power (BOP) | Instrument of policy (16th–early-20th c.) to prevent power dominance (Europe 1815–1914). Hedley Bull: BOP prevented a universal empire, protected states’ independence & fostered diplomacy. Derived term — Balance of Terror (US–USSR nuclear deterrence). |
| Choke Points | Naval-diplomacy term — an international strait whose control can affect commercial transit. |
| Civil War | Internal violence to control the state’s apparatus. Three causes: end colonialism, secession, reunion. E.g., India’s intervention in East Pakistan (Bangladesh) Muktijuddho, 1971. |
| Cold War | Term coined by journalist H.B. Swope; popularised by Walter Lippmann — “no war, yet no peace.” US–Soviet ideological tension after WWII. |
| Colonialism | A form of imperialism controlling another country’s politics & economy (15th–19th c.: Portugal, Britain, France, Holland, Spain). Related: neo-colonialism, internal colonialism (Central Asian Republics post-USSR), and decolonisation → ‘Third World’. |
| Deterrence | Issuing a threat of punishment to prevent undesirable behaviour by another state — a power relationship built on negative sanctions. |
| Disarmament | Process to reduce, remove & eliminate identified weapon systems (usually nuclear), aiming at a completely disarmed world. |
| Extradition | One state hands over a fugitive to another; requires an extradition treaty — no duty to extradite without one. |
| Failed Nation States | Post-Cold-War term for states that cannot survive without external aid (Cold-War aid having propped them up). |
| Foreign Aid | A tool of economic diplomacy — a donor uses money to achieve policy goals in a recipient state; can reward behaviour (a power instrument). |
| Free Trade (laissez-faire) | Trade without restrictions; promotes competition, efficiency & interdependence. A free-trade area (abolishing tariffs on identified goods) is a prerequisite for a customs union. |
| Genocide | Systematic extermination of a group. UNGA Genocide Convention passed Dec 1948, in force Jan 1951; Art. 2 = destruction, in whole/part, of a national, ethnic, racial or religious group. |
| Geopolitics | Foreign-policy analysis using geographical variables; dynamic — Saudi oil’s salience may fall as gas-rich Iran/Russia rise. |
| Great Powers | Realist ranking by economic + military capability. First written mention in the Treaty of Chaumont; the Congress of Vienna, 1815 granted great-power status to Austria, Britain, France, Prussia, Russia. In 1944 W.T.R. Fox coined ‘superpowers’. |
| Gunboat Diplomacy | 19th-c. British practice of dispatching the navy to coerce a state/ruler (e.g., to pay debts) — now = naval signalling & power projection. |
| Hegemony | Political, economic or military predominance of one state over others; others respond with opposition, indifference or acquiescence. |
| Hot Pursuit | Legal doctrine (originally maritime, now also land) — a state may pursue an offender beyond its own territory in national interest. |
| Immigration | Voluntary movement for better work/living (unlike a refugee, who is forced); immigrants send remittances home. |
| Junta | An administrative/ruling council — usually a military government (origin: 1808 anti-Napoleon councils, Peninsular War). |
| Military-Industrial Complex (MIC) | Coined by US President Dwight Eisenhower, 1961 (farewell speech) — the govt–defence-manufacturer nexus linking military spending to employment/economy. |
| Multipolarity | An international system with multiple power-poles; popular since the Cold War’s end — US, Japan, EU as poles, India a ‘near-polar’ power. |
| Paradiplomacy | Coined by John Kincaid, 1990 — diplomacy by a sub-national (state/local) government. India’s NE states–Bangladesh ties (Sheikh Hasina’s 2017 visit). |
| Revolution | Sudden, violent change in a state’s governance & value-system; for Marxists a socio-economic change. E.H. Carr & Martin Wight: revolutions breed instability. |
| Sphere of Influence | An outside state’s economic/military exclusiveness over a region — without sovereign control — limiting others’ influence & the target’s autonomy. |
| Tariffs | A tax on imports — for revenue and, at times, protectionism. |
| Treaty & Convention | A written binding agreement (governed by the Vienna Convention, 1969 — the ‘law of treaties’); a state stays a party even if its govt changes. A convention is a special treaty concluding a global issue (e.g., climate change). |
| Protocol | A specialised treaty that permits amendments/alterations to the main treaty text. |
| Signature & Ratification | Simple signature = interest, not binding until ratified (parliament has a say); definitive signature = bound without ratification. Ratification = parliament’s consent to be bound. |
| Veto | Power to unilaterally block an undesirable outcome; a state must possess the capabilities to exercise it. |
Additional Terms in International Relations
| Term | Meaning |
| Asia-Pacific vs Indo-Pacific | Asia-Pacific = Oceania + NE-Asia + SE-Asia; an economic concept. Indo-Pacific = E-Africa to W-Pacific; a strategic-cum-economic concept focused on sea-lanes of communication (SLOCs). |
| Comprehensive National Power (CNP) | A state’s capacity to mobilise strategic resources — economic, military, diplomatic, natural — to achieve its strategic objectives. |
| Hyphenation & De-hyphenation | Hyphenation = viewing two countries together (US saw India–Pakistan as a pair in the Cold War). De-hyphenation (Bush→Trump) let the US build India ties without factoring in Pakistan’s reaction. |
| Joint Naval Exercises | Bilateral/multilateral drills to build joint operational skill (e.g., the MILAN exercise); theme-based. |
| Joint Naval Patrolling | Cooperative naval deployment against piracy, smuggling & illegal fishing. |
| Natural Ally vs Strategic Partner | Natural allies share values (US–Britain, WWII). Strategic partners merely share a threat & pool resources (US–USSR vs fascists). |
| Non-Traditional Security Threats | Beyond military — environmental, economic, societal: migration, poverty, climate change, terrorism, R2P. |
| Nuclear Safety vs Nuclear Security | Safety = safeguarding civilian nuclear infrastructure; security = keeping materials/tech from non-state actors/terrorists. Obama’s 2009 Prague / Nuclear Security Summit; India ratified the CPPNM (2005). |
| Overt & Covert | Overt = open (India’s 1998 nuclear tests); covert = hidden (RAW operations). |
| Research & Analysis Wing (RAW) | India’s external-intelligence agency — created 1968 (first chief R.N. Kao); under the Cabinet Secretariat, answerable to the PM; personnel are ‘research officers’. |
| Strategic Depth | State A boosts its influence in B to block C’s influence in B — e.g., Pakistan in Afghanistan against India. |
| Strategic Restraint | Using diplomacy, not force, to attain objectives; its opposite is ‘resolve’ (willingness to use force). India uses a mix. |
| Tactical vs Strategic Nuclear Warheads | Tactical = short/small-yield, proximate use; strategic = long-range, intercontinental (ICBM). |
| Thucydides Trap | A rising power creates fear in an established power, leading to conflict. |
| War vs Conflict | Conflict = unresolved, undeclared violence (1962 Sino-Indian = a ‘conflict’, neither side declared war). War = officially declared (1971, India declared war on Pakistan). |
| Current Linkage De-hyphenation → India today practises its own de-hyphenation of Israel & Palestine, pursuing independent ties with both; part of the ‘Look West’ policy (2014 onward) alongside India-UAE CEPA & Chabahar. Thucydides Trap → the standard lens for the India–China (and US–China) power transition in current-affairs answers. |
Key Concepts & Terms in Nuclear Diplomacy
| Term | Meaning |
| 123 Agreement | Under Section 123, US Atomic Energy Act 1954, enabling US nuclear commerce. India–US signed one in 1963 (Tarapur) and again in 2007 (after the Hyde Act, 2006), an exception despite India being a non-NPT state. |
| Additional Protocol (AP) | IAEA safeguard agreements; designed 1993 (after Iraq’s violations) to tighten inspections; kept voluntary. India’s AP preserves its right to a military nuclear programme outside IAEA scope. |
| Atomic Energy Act, 1962 | India’s 1948 Act (British-modelled) set up the Atomic Energy Commission; superseded by the 1962 Act — both centralise state control of nuclear activity. |
| Atoms for Peace | Eisenhower’s 1953 UNGA speech — warned of nuclear dangers & proposed peaceful nuclear-tech transfer; India, Pakistan & Iran built early peaceful programmes from declassified knowledge. |
| Civil Nuclear Liability Act (CLNDA), 2010 | Manages supplier liability post the Indo-US deal; India’s supplier-liability clause is seen as unworkable (insurers wary). Total liability capped at 300 million SDR (~US$450 m). |
| First Strike | A nuclear strategy to locate & fully destroy the enemy’s nuclear forces; needs reserves for reprisal. ≠ a ‘first attack’ (a limited strike). |
| First Use | Reserving the right to use nuclear weapons first when conventional defence is uncertain. India has a No-First-Use doctrine. |
| Comprehensive Test Ban Treaty (CTBT) | First proposed by Nehru (1954); text finalised 1996; bans all nuclear testing but is not in force; India refused to sign (opposed at 1996 UNGA with Libya). |
| Conference on Disarmament (CD) | Geneva-based negotiating body: TNCD (1960) → ENCD (1961) → CCD (1969) → CD (1979); negotiated the CTBT & FMCT. |
| Fissile Material Cut-off Treaty (FMCT) | Proposed treaty to ban production of highly-enriched uranium & plutonium; India favours a ban on future production only. |
| Missile Technology Control Regime (MTCR) | Informal 1987 regime (US, UK, Canada, France, Germany, Italy, Japan) banning transfer of missiles carrying >500 kg or with >300 km range; added UAVs in 1992. India joined June 2016 (blocked by Italy in 2015); China is not a member. |
| Peaceful Nuclear Explosion (PNE) | A non-military nuclear explosion (permitted by the NPT). India’s 1974 Pokhran test. |
Key Concepts in International Relations
| Term | Meaning |
| Collective Security | ‘One for all, all for one’ — states enforce peace by threatening the aggressor with collective sanctions/military action; members stay sovereign but give up unilateral force. First attempted by the League of Nations (failed). NATO is collective DEFENCE, not collective security. Post-CW, cooperative security is more popular. |
| National Interest | The analytical tool identifying a state’s foreign-policy objectives. Per Charles Beard, it replaced raison d’état in 16th-c. Europe. Central to Realism and Hans Morgenthau (national interest = acquisition/use of power, esp. military); its root is survival & security. |
Advanced Terms & Concepts
| Term | Meaning & exam-ready facts |
| Aid | Concessional transfer of goods/services between actors — with or without strings; a Cold-War foreign-policy tool (US European Recovery Programme). |
| Ambassador | A career diplomat & the ‘enabling vehicle’ of official state communication. Resident ambassadors emerged in 14th–15th-c. Venice/Milan; formalised by the Congress of Vienna, 1815 (Corps Diplomatique). |
| Capability | The possessions of a state actor used to analyse power — military & economic, and now diplomatic skill too. |
| Economic Sanctions | A form of economic statecraft — an imposer–target relationship using boycotts/embargoes to coerce a policy change. |
| Strategic Partnership (SP) | Deeper than ordinary bilateral relations but short of an alliance — convergence in security, defence & commercial diplomacy; Cold-War origin. For India, the yardstick is the partner’s role vis-à-vis national security/interest, and cooperation only in areas of convergence. |
Types of Diplomacy
| Term | Meaning & exam-ready facts |
| Summit-Style Diplomacy | Leaders meet face-to-face to resolve issues. Term used by Churchill; Lloyd George credited as its initiator. |
| Tracks of Diplomacy | Track-I = official (heads of state/diplomats); Track-II = non-official (NGOs, media, civil society); Multi-track = Louis Diamond’s nine tracks. |
| Backchannel Diplomacy | Secret communication between adversaries for a breakthrough (Obama–Rouhani → US–Iran nuclear deal, 2015). |
| Ping-Pong Diplomacy | US–China table-tennis exchanges (early 1970s) that opened channels → Nixon’s China visit. |
| Soft Power Diplomacy | Coined by Joseph Nye — winning aims without military coercion or economic inducement. |
| White Shipping Agreement | Exchange of information on non-military merchant vessels — builds Maritime Domain Awareness (MDA). |
| Net Security Provider | A country that ensures a stable, secure neighbourhood in its region. |
| Pariah State | A state perceived as an outcast / global pariah. |
Navy classification by reach
| Term | Meaning |
| Brown-Water Navy | Small craft (patrol boats, gunboats) operating mainly in rivers. |
| Green-Water Navy | Offensive capability in the littoral / coastal zone. |
| Blue-Water Navy | Power projection in deep oceans via aircraft carriers — India aspires to this. |
Terms Used in Economic Integration (the ladder)
Economic integration deepens stage by stage. Read this ladder once and dozens of FTA/CEPA headlines fall into place:
| Stage 1 · TIFA / BIT TIFA (Trade & Investment Framework Agreement) = usual first step to expand trade & settle disputes (ASEAN-US 2009). BIT (Bilateral Investment Treaty) = invite FDI & protect investors. |
▼
| Stage 2 · PTA Preferential Trade Agreement — reduces tariff & non-tariff barriers; a prelude to an FTA. |
▼
| Stage 3 · FTA Free Trade Agreement — eliminates tariffs on goods & services; boosts specialisation & division of labour. |
▼
| Stage 4 · CECA / CEPA Beyond an FTA. CECA adds an investment regime; CEPA adds investment + intellectual property + fair competition. |
▼
| Stage 5 · Common Market Free movement of capital & labour (plus goods, services, investment); removes technical, physical & fiscal barriers. |
▼
| Stage 6 · Customs Union ★ Highest form — a common external import duty + complete free trade within the group. |
Three-World Theory
| Term | Meaning |
| First World | The rich capitalist West, led by the US (Cold-War coinage). |
| Second World | States economically & militarily stronger than the Third World, led by the USSR. |
| Third World | The decolonised, less-industrialised, relatively poor states (mostly non-aligned; the tag also attached to communist Cuba). |
| Current Linkage — from ‘Third World’ to ‘Global South’ The Brandt Line (1980) split the world into a richer North & poorer South — the Global South (Asia, Africa, Latin America) is the modern successor of the ‘Third World’ idea. India positions itself as a bridge / ‘Voice of the Global South’: it hosted the 3rd Voice of the Global South Summit (2024) — 123 countries, theme Vasudhaiva Kutumbakam — and used its G20 presidency to induct the African Union into the G20. |
