Paper 3B · Global Politics

Power and developments

What power is, who has it, how it is distributed, and what kind of state wields it best. The conceptual core of Paper 3B Global Politics - covers types of power, polarity, state classification, systems of government and development. Tested through Q3 and synoptic questions across the paper.

Power is the central concept of global politics. Every other question on Paper 3B - sovereignty, global governance, regionalism, the role of international law - is in the end a question about who has power, what kind, and how it is being distributed. The Edexcel spec breaks this down into five sub-sections: types of power, the classification of states, polarity, systems of government, and development. This walk-through opens with the four types of power, then takes you through polarity from 1945 to today, then state classification and systems of government, then development, and finishes with a worked Q3 answer.

Part 1

What is power in global politics?

The foundation everything else builds on.

The political scientist Robert Dahl's shorthand definition - power is the ability to get others to do something they would not otherwise do - is the starting point. But in global politics this works in several different ways. A state can coerce another with military force. It can attract another by offering an example or culture it wants to copy. It can shape the rules of the international system so other states play by its terms even without being told to. These are three different forms of power - and Joseph Nye's distinction between hard and soft power, plus Susan Strange's notion of structural power, gives the Edexcel student the toolkit the exam expects.

The fourth distinction - smart power - is Nye's later term for the deliberate combination of hard and soft tools in a single foreign-policy strategy. The Obama administration adopted the phrase officially; the Biden administration's response to Russia's 2022 invasion of Ukraine (sanctions plus military aid plus diplomatic coalition-building) is a textbook example.

One distinction to keep in mind throughout. Power is not the same as influence. Influence is the outcome - changing what others do. Power is the resource - what gives you the ability to do that. A state can have lots of military power but little influence if it doesn't use it well, and vice versa.
Part 2

The four types of power

Scroll - each type lights with its key examples and how it shows up in current global politics.

The Edexcel spec recognises three types of power explicitly - hard, soft and structural - and the textbook adds smart power as the deliberate combination. The five Edexcel theorists to know across this whole topic are Joseph Nye (hard/soft/smart), Susan Strange (structural), Kenneth Waltz and John Mearsheimer (realist views of state power) and Francis Fukuyama (development and liberal democracy). Scroll through each type; the figure beside you holds all four types with the one you are reading lit.

Step 1

Four types, one shared question

Hard, soft, structural and smart. All four answer the question: how do states get others to do what they want? They differ on the means - coercion, attraction, rule-setting, or deliberate combination.

Step 2

Hard power

Coercion and inducement. Military force, economic sanctions, and the threat of either.
Key theorists: Kenneth Waltz and John Mearsheimer - realists who treat hard power as the bedrock of international politics. Power as material capability: how many troops, how many missiles, how big the economy.

Hard power gets compliance through sticks and carrots. Military: deployment, threat, actual use. Economic: sanctions, tariffs, conditional aid, the freezing of foreign assets. Realists treat hard power as the only kind that ultimately counts because in a self-help system there is no higher authority to call.

Current example: Russia's 2022 invasion of Ukraine - the bluntest current use of military hard power. Western response combined hard power (sanctions, frozen reserves, weapons supply) with diplomatic coalition-building.
Limit: Hard power is expensive and often produces backlash. The US in Iraq 2003 and Afghanistan (2001-2021 withdrawal) showed military hard power could topple regimes but could not produce stable client states.
Step 3

Soft power

Attraction and emulation. Culture, political values, institutions, foreign policy others want to be associated with. Joseph Nye coined the term in 1990.
Key theorist: Joseph Nye (Harvard) - the foundational thinker. Three sources: culture, political values, foreign policy when seen as legitimate.

Soft power gets compliance through being attractive. Hollywood, K-pop, the global appeal of a free press, the appeal of joining the EU. States with strong soft power get cooperation without coercion. The 2024 BBC/Brand Finance Global Soft Power Index typically ranks the US, UK, Germany, Japan and France at the top.

Current example: South Korea's K-pop and K-drama exports - a deliberate national strategy that turned cultural product into geopolitical reach. EU enlargement as soft power: states queue to join.
Limit: Soft power decays. The post-2016 Trump-era erosion of US standing, the Saudi handling of the 2018 Khashoggi killing, and the West's perceived double standards on Israel-Gaza versus Russia-Ukraine all damaged soft power.
Step 4

Structural power

Rule-setting. The power to shape the frameworks within which others operate - finance, security, knowledge, production. Susan Strange's 1988 concept.
Key theorist: Susan Strange (LSE). Structural power has four faces: security, production, finance, knowledge.

Structural power is the deepest because it sets the rules others play by. The dollar's role as the world reserve currency gives the US structural financial power - the ability to sanction Iran through SWIFT, freeze Russian reserves, or pressure third-country banks to comply. NATO gives the US structural security power in the Atlantic. China's Belt and Road, the Asian Infrastructure Investment Bank (AIIB) and BRICS bank are attempts to build alternative structures.

Current example: SWIFT and the US dollar - structural financial power. Belt and Road Initiative (BRI) - China's bid to build alternative structural power through infrastructure and finance, with 150+ partner countries.
Limit: Building rival structures is slow. China has spent over a decade and trillions of dollars and has shifted but not displaced the dollar system. Structural power is sticky.
Step 5

Smart power

The deliberate combination of hard and soft power in coherent foreign-policy strategy. Joseph Nye coined the term in 2003; the Obama and Biden administrations adopted it.
Key theorist: Joseph Nye again. Smart power = "knowing when to use which combination of hard and soft tools."

Smart power is recognition that the textbook distinction between hard and soft is too clean. Real foreign policy combines both. The 2022 Western response to Russia's invasion of Ukraine - sanctions plus weapons plus diplomacy plus the public broadcast of moral leadership - is the textbook current case.

Current example: Western response to Russia 2022-2024 - hard (sanctions, frozen reserves, weapons supplied via NATO members) plus soft (Zelensky as global media figure; rallying democratic publics).
Limit: Coordinating hard and soft tools across many actors is difficult. The Western coalition's response to Israel-Gaza after October 2023 showed how soft power suffers when allies are divided on the moral question.
Step 6

How the four interact

Hard power can produce short-term compliance but burns soft power. Soft power without hard backing is often ignored. Structural power persists across changes of regime - the dollar system survived four US presidents on either side. Smart power is the deliberate orchestration of the other three.

Exam expects you to distinguish them precisely and to identify which form is at work in any current example. A 2024 question on Chinese power, for instance, requires hard (PLA build-up), soft (Confucius institutes, scholarship), structural (BRI, AIIB) and a judgement on whether China has yet matched the US.

Four types of power across global politics.

Case: Western Ukraine response 2022-24.
Part 3

Polarity - how power is distributed

Scroll - each era lights with its distribution of power and the contemporary debate.

Polarity is how many great powers shape the international system at one time. The post-1945 era moves through three forms: bipolarity (Cold War 1945-1991), the unipolar moment (1991-c.2008), and the contested return of multipolarity (2008-present). Each polarity has different implications for stability, conflict and the role of international institutions.

Step 1

Three eras, three polarities

Bipolar (1945-91), unipolar (1991-c.2008), multipolar (now). The figure beside you holds all three eras with the one you are reading lit.

Step 2

Bipolarity (1945-1991)

Two superpowers dominate: the US and USSR. Each leads a bloc - NATO and the Warsaw Pact. Proxy wars - Korea, Vietnam, Afghanistan, Angola - but no direct great-power war. Realists (Kenneth Waltz) argued bipolarity was relatively stable because each side could calculate the other's intentions and capabilities.

Stability: Realist view: stable. Mutually assured destruction (MAD) prevented direct war.
Conflict: Confined to proxy wars on the periphery.
Institutions: UN deadlocked at the Security Council - vetoes used routinely. Cold War limited UN effectiveness.
Step 3

The unipolar moment (1991-c.2008)

USSR collapses 1991. United States the sole superpower militarily, economically and culturally. The "Washington Consensus" of liberal democracy and free-market capitalism appears to triumph (Francis Fukuyama's The End of History, 1992). NATO enlargement east; expansion of EU; UN intervention in the Balkans 1990s; US-led wars in Afghanistan 2001 and Iraq 2003.

Stability: Contested. Some saw it as stable hegemony; others saw it as US over-reach (Iraq) breeding backlash.
Conflict: Smaller wars (Balkans, Iraq, Afghanistan); no peer competitor to the US.
Institutions: Expanded influence of UN, WTO (founded 1995), NATO, EU - liberal institutional order at its peak.
Step 4

Multipolarity returns (2008-present)

The 2008 financial crisis dented Western economic confidence. China's GDP overtook Japan in 2010; Russia's resurgence under Putin from 2007; the rise of regional powers (India, Brazil, Turkey, Iran, Gulf states). The 2022 Russian invasion of Ukraine and the 2023-24 Gaza war exposed deep divisions in the international order. By 2024 China's GDP (PPP) had overtaken the US, and the BRICS+ grouping had expanded to challenge Western institutions.

Stability: Contested. Realists (Mearsheimer) argue multipolarity is unstable - more potential conflicts, miscalculation more likely. Liberals say institutions can manage it.
Conflict: Return of great-power competition: US-China rivalry; Russia-NATO confrontation; regional wars in Ukraine, Gaza, Sudan.
Institutions: Strained. UN Security Council paralysed on Ukraine and Gaza. BRICS, AIIB, SCO build alternative structures. WTO largely sidelined by US-China trade war.
Step 5

Where are we now?

The most defensible reading is that we are in a contested transition from a unipolar moment to a multipolar order in which the US remains the leading power but no longer the unrivalled one. China is the only state with comparable scale across all four forms of power. Russia has hard military power but limited soft and structural reach. The EU has structural and soft power but no unified hard power. India, Brazil and Turkey are rising regional powers.

Exam expects you to take a position with evidence. The default 2026 reading: emerging multipolarity, with US-China bipolar competition embedded inside a wider multipolar order.

Three polarities since 1945.
Bipolar 1945-1991US + USSR
Stability: realist view = stable.
Conflict: proxy wars.
UN: deadlocked.
Unipolar 1991-c.2008US sole superpower
Stability: contested - US over-reach.
Conflict: US-led wars; no peer.
UN/WTO: liberal order at peak.
Multipolar 2008-nowUS + China + others
Stability: realists worried; liberals defend.
Conflict: great-power return.
UN: strained; BRICS+ rising.
Part 4

State classification and systems of government

How states are ranked and what kind of regimes hold global power.

The spec asks you to classify states by power and by political system. Both classifications matter because the question of who holds global power is partly a question about which kind of regime is rising.

State classification

The standard ladder runs: superpower · great power · emerging power · regional power · middle power · small state. A superpower has global reach across all four types of power; a great power has substantial reach but is not globally dominant; emerging powers are gaining capability rapidly; regional powers dominate their neighbourhood.

Category Definition Current examples
SuperpowerGlobal reach across hard, soft and structural power; able to project force anywhere; sets the rules of the system.USA (only undisputed example today). China contested.
Great powerSubstantial military and economic capability; permanent seat on UNSC; ability to project force regionally and influence globally.China, Russia, UK, France, plus arguably India.
Emerging powerRapidly growing capability and global ambition; not yet at great-power scale.India, Brazil, Indonesia, Turkey, Saudi Arabia.
Regional powerDominant in its region but limited reach beyond.Iran (Middle East), South Africa (sub-Saharan Africa), Nigeria, Egypt, Australia, Mexico.
Middle powerSignificant but not regionally dominant; often relies on diplomacy and multilateralism.Canada, Norway, Sweden, South Korea, Argentina.
Small stateLimited capability; often most active in regional bodies.Estonia, Singapore, Costa Rica, New Zealand.

Systems of government

The Edexcel spec recognises a spectrum: liberal democracy (free elections, rule of law, individual rights, free media), illiberal democracy (elections held but rights and media restricted), authoritarian (no meaningful elections, single-party or autocratic rule). The question of which kind is best at delivering both political stability and economic development is the spec's "development and spread" question.

SystemFeaturesExamples (2026)
Liberal democracyFree fair elections; rule of law; protected rights; free press; checks on executive.UK, USA, Germany, France, Japan, Canada, Australia.
Illiberal democracyElections held but media curbed, courts politicised, opposition harassed.Hungary under Orban, Turkey under Erdogan, India under Modi (contested), Tunisia post-2021.
AuthoritarianNo meaningful elections; one-party or single-leader rule; tight media control.China, Russia, Saudi Arabia, Iran, North Korea.

The "third wave" of democratisation (Samuel Huntington, 1991) saw the number of democracies grow from ~40 in 1974 to ~120 by the late 1990s. Since c.2006 democracy has receded: Freedom House and V-Dem's annual reports document a steady decline. The 2010s saw democratic backsliding in Turkey, Hungary, Poland, India, Brazil under Bolsonaro and the US itself. The exam expects you to engage with this trend.

Part 5

Development and spread

What development is, what drives it, and what gets in its way.

Development is the broad improvement in the human condition - longer life, better health, more education, higher incomes, greater rights. The most influential measure is the UN's Human Development Index (HDI) - life expectancy + education + GDP per capita combined - first published in 1990. The Millennium Development Goals (2000-2015) and Sustainable Development Goals (2015-2030) framed the international agenda.

Drivers of development: economic growth, trade openness, foreign direct investment, technology transfer, political stability, rule of law, education and health investment. Obstacles: conflict, weak institutions, corruption, climate vulnerability, debt, dependency on commodity exports, the so-called "resource curse." The most striking development success since 1980 is East Asia - China lifting ~800 million out of poverty, plus the high-income status of South Korea and Singapore. The most stubborn challenge is sub-Saharan Africa, where growth has not consistently translated into broad-based development.

Theoretical debate: Modernisation theory says all countries can develop along a similar path if they adopt liberal-democratic and market-economic institutions (Fukuyama's position). Dependency theory says the global economy is structured to keep poorer countries poor through unequal exchange. Post-development theorists argue development itself is a Western construct that should be challenged. The exam typically tests this through "to what extent has globalisation reduced global inequality" or "to what extent has Western-style democracy proved necessary for development" questions.

The China question sits in the middle of this debate. China's rise on every development indicator over four decades happened under an authoritarian one-party state, not a liberal democracy - challenging the modernisation thesis. But whether the Chinese model is replicable elsewhere, or whether it depends on China-specific factors, remains contested.

Into the exam - essay resources and worked questions

Direct links to every Paper 3B power-related resource on Panther, plus a worked answer.

Power and developments is tested directly by Paper 3B Q3 and is invoked synoptically across Q1 (globalisation), Q2 (global governance) and Q4 (regionalism). The strongest answers move fluently between the four types of power, evidence them with specific contemporary examples, and reach a clear position on the current polarity.

Likely 24-mark questions to practise.

24To what extent does the international system remain unipolar in 2026?

Approach: Para 1 case for continued US primacy - largest military budget; dollar dominance (Strange's structural finance); soft power top of every league table; NATO expansion 2023-2024. Para 2 case for multipolarity - China GDP (PPP) past US; BRICS+ expansion; Russia 2022 invasion as deliberate challenge to Western order; Gaza divisions show US influence has limits. Para 3 hybrid view - bipolar US/China at the top of a wider multipolar order; Mearsheimer's prediction of US-China structural conflict. Judgement: not unipolar; not yet fully multipolar; transition.

24To what extent is hard power still the most important form of power?

Approach: Para 1 case for hard power - Russia 2022 invasion; Gaza war; US deterrence in Taiwan Strait; sanctions; the brute fact that war returned to Europe. Para 2 against - soft power's reach (K-culture; EU enlargement); structural power (Strange) - the dollar system shapes outcomes without firing a shot. Para 3 - smart power (Nye) reconciles: hard and soft are inseparable in real strategy. Judgement: hard power remains foundational but is insufficient alone; smart-power combinations dominate.

24To what extent has the spread of democracy stalled?

Approach: Para 1 case for stall - Freedom House and V-Dem data on democratic backsliding since 2006; Hungary, Turkey, India, US 2016-21; authoritarian China rising; Russia 2022. Para 2 case against - global number of democracies still high vs 1974; new democracies in places like Malawi, Brazil 2022 recovery, peaceful 2024 UK transition; Huntington's third wave largely intact. Para 3 - the contest is between democratic resilience and authoritarian re-emergence; Indo-Pacific democracies (Japan, South Korea, Taiwan, Indonesia) are the test. Judgement: stalled but not reversed.

One worked essay

To what extent does the international system remain unipolar in 2026? (24 marks)
Line of argument: The international system is no longer unipolar. The US remains the leading power across all four types of power but is not the unrivalled power it was in the 1991-2008 unipolar moment. The most defensible reading is bipolar US-China competition embedded in a wider multipolar order - a structural shift driven by China's economic rise, Russia's military reassertion and the emergence of confident regional powers.
Paragraph One - The case for continued US primacy
  • US military budget still exceeds the next ten combined; only navy with truly global reach; deep alliance system (NATO, AUKUS, Japan-South Korea).
  • Structural financial power: the dollar remains the world reserve currency (Susan Strange's analysis of structural finance); SWIFT exclusion gives the US sanctions leverage no other state matches.
  • Soft power: US tops the 2024 Global Soft Power Index; Hollywood and US tech (Apple, Google, Microsoft) shape global culture; English remains the lingua franca of business and science.
Paragraph Two - The case for emerging multipolarity
  • ×China's GDP (PPP) overtook the US c.2017; manufacturing share roughly 30% of global; PLA Navy now exceeds US Navy in ship numbers; BRI in 150+ countries.
  • ×Russia 2022 invasion of Ukraine - a deliberate challenge to the post-1991 European order; Western response unified the West but did not deter Russia.
  • ×BRICS+ expansion 2024 to include Iran, UAE, Egypt, Ethiopia builds alternative structural reach; AIIB, SCO and BRICS bank chip away at the dollar system.
  • ×Regional powers asserting themselves: India under Modi (G20 host 2023); Turkey across the Middle East; Saudi Arabia rebalancing toward China.
Paragraph Three - The hybrid reading
  • ×The most defensible reading is bipolar US-China competition embedded in a wider multipolar order. John Mearsheimer's prediction of structural US-China rivalry now describes the central axis of global politics.
  • ×Gaza war 2023-24 exposed the limits of US influence - Israel, an ally, ignored repeated US pressure for restraint; Global South largely sided against the Western position.
  • But China has not closed the gap on soft power, alliance networks or structural finance. Russia has hard military power but no soft or structural reach. The US still sets more rules than anyone else - but no longer all of them.

Judgement. The unipolar moment ended c.2008 and has not returned. The current system is not yet fully multipolar in the 19th-century sense - too much depends on the US-China relationship. The most defensible 2026 reading is bipolar US-China competition embedded in a multipolar order, with the EU as a structural and soft-power actor, Russia as a hard-power challenger, and emerging powers like India, Brazil and Turkey making the system more crowded. The system is no longer unipolar.
