Book summary “Global politics”: summary

Introduction

You often struggle to make sense of a world where traditional diplomacy no longer explains financial crashes, pandemics, or digital warfare. Andrew Heywood argues that world politics can no longer be understood through a purely state-centric lens and requires a mixed-actor model of complex interdependence.

The book traces the historical evolution of the international system and examines the core theoretical frameworks used to interpret global affairs. You will explore how economic globalization, state power, cultural identities, and shifting military threats shape the twenty-first-century order.

• Who holds real power in a globalized world?
• How do non-state actors challenge traditional state sovereignty?
• Can international institutions prevent future systemic conflicts?

1. From International to Global

State-centrism and Sovereignty

Modern international order is historically rooted in the Peace of Westphalia. That 1648 settlement ending the Thirty Years War established state sovereignty as the primary organizing principle.

The Westphalian system established that states enjoy sovereign jurisdiction and independent control within their own territory. Relations between states are structured upon their mutual recognition of sovereign independence and legal equality.

World politics can no longer be understood through a purely state-centric lens and requires a mixed-actor model.

While states retain a monopoly on ultimate coercive power, their ability to act is increasingly challenged and shaped by non-state actors. You find that transnational corporations, NGOs, religious movements, and influential individuals now share the global stage.

From Independence to Interdependence

The traditional billiard ball model of self-contained, independent states has been superseded by a cobweb model of complex interdependence.

Under conditions of complex interdependence, states are drawn into cooperation because transnational challenges cannot be solved by any single state acting alone. These shared dilemmas include economic crises, climate change, and nuclear proliferation.

Because there is no higher authority than the state, international politics traditionally operates as a self-help system. However, the 1945 watershed year marked the expansion of the framework of global governance to manage these collective dilemmas.

The traditional strict divide between domestic and international politics has been eroded by cross-border transnationalism. The growth of global financial flows, digital communications, and transnational issues means state borders have become porous. During the 2007-09 global financial crisis, economic vulnerability clearly demonstrated how difficult the inside/outside divide is to uphold.

The Globalization Debate

Globalization is not a single process but a multifaceted complex of economic, cultural, and political developments rooted in worldwide interconnectedness.

• Economic globalization absorbs national economies into a single global market.
• Cultural globalization standardizes images and information across borders.
• Political globalization shifts policymaking responsibilities to international organizations.

By the mid-1990s, a consensus emerged that globalization was changing everything, leading to intense academic debate.

Academic debate on the nature and significance of globalization is divided into three primary positions.

Hyperglobalists see globalization as a revolutionary, profound shift that erodes state power. Sceptics argue that globalization is exaggerated and that the state remains dominant. Transformationalists view globalization as a historically unprecedented process that profoundly reorganizes modern societies and states without erasing state power.

2. Historical Context of Global Politics

Modern global politics has been shaped by total wars, the collapse of empires, decolonization, and the bipolar struggle of the Cold War.

From World Wars to Decolonization

World War I marked the beginning of the short twentieth century, representing the first total, industrialized war that was precipitated by imperial competition, nationalism, and alliance systems. You can trace the end of the belle époque era of globalization to this catastrophic breakdown.

Archduke Franz Ferdinand was assassinated in June 1914 by the Black Hand, a group of Serbian nationalists.

Some 65 million men were mobilized during World War I. Over 8 million combatants died in World War I. About 10 million civilians were killed in World War I or perished in the Spanish influenza epidemic of 1918-19.

World War II was the largest military confrontation in history, rooted in the flawed Versailles peace settlements, the 1929 economic crisis, and aggressive Nazi and Japanese expansionism.

Nazi Germany and the Soviet Union invaded Poland on 1 September 1939, and Japan attacked the US military base at Pearl Harbor on 7 December 1941.

Over 90 million combatants were mobilized in World War II. Estimates of World War II dead range from 40 to 60 million.

The dismantling of European empires after 1945 triggered the most intense period of state construction in world history, rapidly expanding the United Nations and transforming the international system into a global order.

The British Empire brought 49 new states into existence by 1980, including India's independence in 1947.

European decolonization more than tripled UN membership from about 50 states in 1945 to over 150 states by 1978.

The Cold War and the Post-Cold War Era

The Cold War dominated post-1945 global politics through a bipolar struggle between the US-led capitalist West and the Soviet-led communist East until the sudden collapse of communist regimes between 1989 and 1991.

Winston Churchill used the term iron curtain in his 1946 speech in Fulton, Missouri, to describe the division of Europe.

US forces in Europe dropped from 3.5 million in May 1945 to 400,000 the following March, and eventually to 81,000.

The post-Cold War era of initial liberal optimism was disrupted by the emergence of transnational terrorism and conflict rooted in Middle Eastern historical and political crises.

A total of 2,995 people were killed in the September 11, 2001 terrorist attacks when hijacked airliners struck the World Trade Center, the Pentagon, and a field in Pennsylvania.

3. Theories of Global Politics

Mainstream theories like realism and liberalism compete with critical perspectives to explain the balance between conflict and cooperation.

Realism and Liberalism

Realism asserts that global politics is driven primarily by power and self-interest, operating within an international state of nature characterized by anarchy. Classical realism explains power politics through human egoism, while neorealism or structural realism attributes it to international anarchy and the absence of a central authority. This forces states into a system of self-help and permanent insecurity known as the security dilemma.

Liberalism contends that global affairs tend toward harmony, cooperation, and peace through economic interdependence, democratization, and international institutions. Unlike realists, liberals believe that competing state interests are ultimately reconcilable.

You can categorize these liberal approaches into specific models:

• commercial liberalism emphasizes the pacifying effects of free trade;
• republican liberalism links peace to democratic governance through the democratic peace thesis;
• neoliberal institutionalism highlights the role of international organizations in fostering absolute gains and complex interdependence.

Critical Approaches and Post-positivism

Critical theories challenge mainstream realism and liberalism by exposing hidden power asymmetries, systemic inequalities, and ideological hegemony. Encompassing Marxism, neo-Marxism, constructivism, poststructuralism, feminism, green politics, and postcolonialism, critical approaches argue that theory and practice are intimately linked. Many adopt a post-positivist stance, viewing reality as inter-subjective rather than objectively given through dependency theory.

Global interconnectedness fosters cosmopolitanism and ethical frameworks that view the individual human being as the ultimate unit of moral concern across borders. Cosmopolitan theorists argue that shared global awareness constitutes the world as a single moral community, generating universal obligations of human rights and justice. This view is contested by communitarians who argue that moral values must remain locally grounded through cultural relativism.

4. The Economy in a Global Age

Modern economic globalization marks a qualitative shift toward deep integration into a single borderless global economy. Driven by structural capitalist expansion and technological breakthroughs, national economies have been absorbed into an interlocking global economy where capital and production flow instantly.

Economic globalization and neoliberalism have created deep integration while generating systemic financial vulnerabilities and state transformations.

Technological milestones facilitating globalization range from the telegraph in 1857 and telephone in 1876 to optical fibres in the late 1960s, commercial silicone chips in 1971, and personal computers in 1981. By 2012, roughly 5 trillion dollars were traded each day in global currency markets.

Capitalism and Neoliberalism

Neoliberalism emerged as a counter-revolution to reverse post-war state intervention and Keynesianism by promoting free markets and rolling back the state. Academic exponents like Hayek and Friedman attacked Keynesian tax-and-spend policies blaming them for 1970s stagflation. The ideology manifested as Reaganism in the US and Thatcherism in the UK, eventually spreading globally through the Washington consensus and structural adjustment programs.

The earliest experiment in neoliberalism occurred in Chile after the 1973 CIA-backed coup overthrowing Salvador Allende. General Pinochet introduced sweeping market reforms advised by the Chicago boys during his tenure.

Capitalist economies display distinct institutional models:

• Enterprise capitalism relies on untrammelled market competition, individualism, and shareholder primacy.
• Social capitalism attempts to combine market competition with social cohesion and welfare protections.
• State capitalism features cooperative, long-term relationships where the state guides investment and research.

Enterprise capitalism minimizes public ownership while emphasizing high productivity and labour flexibility. Social capitalism relies on long-term investment, industry-wide wage negotiations, and comprehensive welfare systems. State capitalism uses relational markets and interlocking share ownership to achieve sustained growth without relying strictly on liberal democratic institutions.

Transnational Corporations and Crises

Transnational corporations exert massive economic and political influence, often rivaling sovereign states in economic size. TNCs account for roughly half of world manufacturing and over seventy percent of world trade. Their ability to shop around for low taxation and cheap labor gives them a strategic advantage over national governments.

Based on a comparison between corporate sales and countries GDP, 51 of the world's 100 largest economies are corporations. General Motors is equivalent in size to Denmark, Wal-Mart to Poland, and Exxon Mobil to South Africa.

The Great Depression demonstrated the dangers of laissez-faire inaction and beggar-thy-neighbour protectionist policies during economic slumps. Following the 1929 Wall Street Crash, the Hoover administration kept public spending low and sought balanced budgets, worsening the contraction. On Black Thursday, 24 October 1929, 13 million shares changed hands in a single day, followed by 16 million shares on 29 October.

The 2007-2009 global financial crisis exposed the vulnerabilities of deregulated neoliberal financialization and sub-prime mortgage lending. Triggered by toxic debt in the US, the crisis brought global capitalism to the brink of systemic failure.

In September 2008, Fannie Mae and Freddie Mac were bailed out by US Federal authorities. Lehman Brothers filed for bankruptcy, AIG received an 85 billion dollar rescue package, and Wachovia was absorbed by Citigroup after absorbing 42 billion dollars of bad debt. G-20 members contributed 500 billion dollars to global reflation, and traditional government shifted toward multi-level governance.

5. The State and Foreign Policy in a Global Age

Foreign policy decision-making and state power are shaped by internal bureaucratic processes, cognitive filters, and multi-level governance.

Foreign Policy Decision-Making

The rational actor model assumes that foreign policy decisions are made through a logical, cost-benefit calculation to maximize national interests. Realist theorists apply this approach to international politics, arguing that foreign policy is guided by the single overriding goal of ensuring state survival and the pursuit of power.

Incrementalism suggests that decisions are rarely based on clear-cut objectives, but rather on small, exploratory adjustments to changing circumstances. The UK and France pursued a policy of appeasement toward Hitler's Germany in the 1930s in the hope of avoiding war through incremental concessions.

Bureaucratic and organizational models open the black box of the state to show how internal government structures and inter-agency bargaining shape decisions. Graham Allison pioneered this approach by examining US and USSR decision-making during the 1962 Cuban Missile Crisis.

Cognitive and belief-system models demonstrate that political behavior is heavily structured by perception, values, and psychological filters rather than pure objective reality. Anthony Eden viewed Egyptian leader Nasser as a second Hitler during the 1956 Suez Crisis, illustrating ethnocentric misperception.

Society and Civil Society in a Global Age

Since the 1960s, centralized state power has frequently faced a countervailing trend toward localization and political decentralization. India adopted a US-style federal system in 1947, Spain created 17 autonomous communities after Franco's death in 1975, France established 22 regional councils in 1982, and the UK introduced a Scottish Parliament, Welsh Assembly, and Northern Ireland Assembly in the late 1990s.

Modern societies are characterized by a transition from close, fixed social bonds to more fluid, individualized, and atomized arrangements. Ferdinand Tönnies distinguished between Gemeinschaft found in traditional societies and Gesellschaft found in industrial and urban societies.

The information age and new communication technologies have transformed society into an information-based network structure that bypasses traditional national borders. US President Bill Clinton likened China's attempts to control the Internet to trying to nail Jell-O to the wall.

The widening of global connectedness has generated a liquid society marked by pervasive uncertainty, manufactured risks, and tragic individualization. Ulrich Beck and Zygmunt Bauman analyzed how the transition from solid modernity to liquid modernity leaves individuals to cope with systemic uncertainty entirely on their own.

Cultural globalization acts through deterritorialization and time-space compression to spread consumer capitalism, global brands, and materialist values worldwide. Naomi Klein critiqued lifestyle branding and corporate domination in her book No Logo, while Benjamin Barber described a commercially homogeneous McWorld.

Global civil society has emerged as a transnational realm of non-governmental organizations and social movements acting as a counterweight to corporate globalization. NGO coalitions successfully campaigned for the 1992 Rio Earth Summit, the 1997 treaty banning landmines, and the establishment of the International Criminal Court in 2002.

6. Identity, Culture and Challenges to the West

Nationalism, identity politics, religious fundamentalism, and postcolonial movements challenge Western universalism and cultural hegemony.

Classical nationalism links the concept of the nation with popular sovereignty and the principle of national self-determination, aiming to construct a nation-state. Rooted in Jean-Jacques Rousseau's idea of the general will, nineteenth-century European nationalists fought against autocratic multinational empires to achieve statehood and liberal republicanism. The unification of Italy and Germany in 1871 where nationalist goals coincided with the ambitions of powerful states like Piedmont and Prussia. Additional milestones include 1947 for the independence of India and 1990 for the independence of Namibia as Africa's last remaining colony.

Expansionist nationalism departs from classical self-determination by promoting national chauvinism, militarism, and doctrines of racial or ethnic superiority. German Nazi Aryanism portraying the German people as a master race destined for world domination backed by virulent anti-Semitism.

Nationalism and Migration

International migration has intensified in the modern era, challenging state sovereignty and creating complex transnational communities and diasporas. Mexican immigration into the USA, forming the most crossed border in the world driven by economic imbalances and push factors. In 2010, there were 214 million international migrants up from 81 million in 1970, representing 3.1 per cent of the world's population. By 2012, there were 28.8 million internally displaced persons compared to 15.4 million refugees.

Remittances from international migrants provide vital financial flows to developing countries, often vastly exceeding official international aid. Remittances constituted Mexico's second largest source of foreign revenue after petroleum, reaching $22.45 billion in 2012. Global remittance flows reached $501 billion in 2011, with $372 billion going to developing countries.

Nationalism has experienced a powerful revival in the post-Cold War era through state self-assertion, ethnic nationalism, and anti-globalization resistance. The rise of Hindu nationalism in India under the BJP and the leadership of Vladimir Putin in Russia leveraging fuel nationalism and state power. Jean-Marie Le Pen gained 18 per cent of the vote in the 2002 French presidential election within the 143.3 million population of the Russian Federation context.

Cultural Conflict and Religious Revivalism

Identity politics has emerged as a challenge to Western universalist liberalism, framing subordination in cultural terms and seeking empowerment through self-assertion. The black consciousness movement and Black Power movement used consciousness-raising and cultural self-assertion to confront dominant white culture.

Samuel Huntington's clash of civilizations thesis argues that post-Cold War global conflict is primarily cultural and civilizational rather than ideological or economic. Post-September 11 conflicts were widely interpreted through the lens of an emerging clash between Islam and the West.

Religious revivalism and fundamentalism reject the separation of religion and politics, treating faith as an overarching program for social and political regeneration. The 1979 Islamic Revolution in Iran brought Ayatollah Khomeini to power as the leader of the world's first Islamic state. Worldwide, 1.5 to 1.7 billion Muslims represent over one fifth of the population across at least 49 countries having a Muslim majority.

Postcolonialism and the assertion of Asian values seek to dismantle Western cultural hegemony and establish alternative non-Western political traditions. The 1993 Bangkok Declaration issued by Asian state representatives advocated for taking cultural differences into account in human rights formulations.

7. Power and Twenty-First-Century World Order

Global power is shifting from hard capabilities and US hegemony toward structural power, soft power, and emerging multipolarity.

Dimensions of Power

Treating power strictly as a collection of tangible national capabilities serves to rank states hierarchically but fails to explain why powerful nations sometimes lose to weaker opponents. The traditional capabilities approach assesses objective factors like population, military size, geographic position, and economic development. However, this only defines potential power, as translating resources into political outcomes depends heavily on subjective factors like national morale, leadership, strategy, and the specific circumstances of conflict.

The USA failed to prevail in the Vietnam War despite possessing massive economic, technological, and military advantages over North Vietnam and the Vietcong.

Relational power defines influence as the ability of one actor to alter another actor's behavior through compellance or deterrence. Relational power equates power with influence rather than raw strength. Compellance forces an adversary to make concessions against its will through active war or threats, which is generally riskier and resource-intensive. Deterrence prevents aggression by demonstrating the likely costs of a military response.

The 2003 invasion of Iraq to achieve regime change exemplifies compellance, whereas maintaining no-fly zones to protect Kurds and Shia Muslims exemplifies deterrence.

Susan Strange defines structural power not as relational coercion, but as the ability to shape the frameworks and rules within which states, people, and corporations relate. Structural power operates through four primary structures that determine how things are done:

• the knowledge structure shaping ideas and perceptions;
• the financial structure controlling access to credit and investment;
• the security structure shaping defense issues;
• the production structure affecting economic development.

Global power is shifting from command-based hard power to co-optive soft power, which relies on attraction, culture, and political ideals. Hard power uses economic carrots and military sticks to change behavior. Soft power shapes preferences through cultural and political legitimacy. Because globalization and digital connectivity allow populations worldwide to evaluate foreign governments, heavy reliance on hard power risks alienating public opinion, leading theorists to advocate for smart power.

US Hegemony and Multipolarity

Neorealists argue that Cold War bipolarity fostered international stability through a balance of terror and mutual deterrence between two nuclear superpowers. The bipolar system, dominated by the US-led West and Soviet-led East, reduced miscalculation because fewer great powers existed and shifting alliances were constrained. Mutually Assured Destruction forced the superpowers into deterrence, resulting in a long peace in Europe lasting from 1945 to 1990, though it fueled neocolonialism and proxy conflicts elsewhere. Key milestones included the formation of NATO in 1949, the Warsaw Pact in 1955, and the erection of the Berlin Wall in 1961.

The collapse of the Soviet Union left the United States as the sole global hegemon, transitioning the liberal moment into a unipolar moment. Unique historical factors shaped US hegemony, including its anti-imperialist political ideology born from the 1776 revolution and its vast internal market expansion. The USA accounted for approximately 40 percent of global manufacturing output in the 1920s and early post-WWII period. US citizens were held hostage during the Iran hostage crisis for 444 days from November 1979 to January 1981. Following the Cold War, US unipolarity brought economic globalization and humanitarian interventions, but also fostered unilateralism and international resentment.

The events of September 11, 2001, triggered the war on terror and a neoconservative foreign policy based on pre-emptive military action and regime change. Guided by the Bush Doctrine, US policy asserted the right to target states harboring terrorists and to project military force to achieve pre-eminence. The subsequent invasions of Afghanistan in 2001 and Iraq in 2003 exposed the limitations of preponderant military power, draining resources and damaging soft power through prolonged counter-insurgency warfare. The 2003 Iraq War was justified using the doctrine of pre-emptive attack against a regime allegedly possessing weapons of mass destruction.

Twenty-first-century world order is shifting toward multipolarity, driven by the rapid economic and structural rise of emerging powers like China and India. China's economic growth, fueled by market reforms since the late 1970s, has made it the world's second-largest economy and largest exporter. China achieved annual GDP growth rates of 8 to 10 percent for almost thirty years, expanding its economy by 90 times between 1978 and 2010 to support a total population of 1.35 billion. While realists warn that rising hegemons inevitably trigger power transition conflicts, liberals argue that deep global economic interdependence encourages multilateral cooperation over geopolitical war.

8. War, Peace and Security

The nature of armed conflict has evolved from traditional interstate wars to asymmetric new wars, postmodern warfare, and nuclear proliferation risks.

Karl von Clausewitz defined war as the continuation of politics by other means in his 1833 publication On War. You can understand war as a rational instrument of state policy driven by cost-benefit calculations. Kenneth Waltz categorized the underlying explanations of war in his 1959 book Man, the State and War into three levels of analysis:

• human nature and biological instincts;
• the internal characteristics and political structures of states;
• structural or systemic pressures within international anarchy.

The Changing Face of War

Post-Cold War armed conflicts differ fundamentally from traditional combat. Since the mid-1980s, 95 per cent of armed conflicts have occurred within states. These identity wars are predominantly civil conflicts fought over ethnic and cultural goals rather than geopolitical objectives.

The break-up of Yugoslavia in the 1990s led to civil wars and ethnic cleansing in Bosnia and Kosovo. These new wars are frequently asymmetrical and blur the distinction between military personnel and civilians.

Postmodern warfare relies heavily on advanced technology rather than mass conflict. Virtual war utilizes computing, satellite tracking, stealth technology, and cruise missiles to achieve swift, decisive goals. The 1991 Gulf War and the 78-day NATO bombing campaign in Kosovo in 1999 showcased the extensive use of high-tech precision weaponry.

Justifying War and Nuclear Proliferation

Just war theory evaluates the morality of armed conflict through distinct criteria. You must separate jus ad bellum, which governs the conditions to enter a war, from jus in bello, which stipulates ethical conduct during combat.

World War II is frequently cited as a conflict fulfilling many just war criteria due to the blatant aggression of the Axis powers, during which 6 million Jewish people and others were murdered by the Nazis. To determine whether you face a just recourse, follow these principles:

• Ensure all non-violent options are exhausted as a last resort before entering war.
• Verify that the war is fought for a just cause such as self-defence.
• Confirm the war is declared by a legitimate authority.
• Maintain a right intention focused on re-establishing peace rather than revenge.
• Ensure there is a reasonable prospect of success.
• Direct force exclusively at military targets under the principle of discrimination.
• Apply proportional force necessary to achieve the military objective.

Nuclear weapons revolutionized security dynamics through Mutually Assured Destruction. By 2002, the USA and Soviet Union jointly held 98 per cent of global nuclear warheads. You face heightened anxiety regarding horizontal proliferation and rogue regimes accessing dual-use technology, as seen when India and Pakistan tested nuclear devices in 1998 and North Korea carried out its first nuclear test in 2006.
