The Cold War and After

For over four decades after the Second World War, world politics was a tense rivalry between two superpowers, the United States and the Soviet Union. They never fought each other directly, yet their contest divided the whole world. This Cold War ended in 1991 when the Soviet Union broke apart. The United States then stood alone as a hegemon, the single dominant power. New centres of power, the EU, ASEAN and China, have since risen to balance it. This arc from a bipolar world to a unipolar one, and now towards a multipolar one, is the backbone of modern international politics.

After 1945, two superpowers stood above all others:

• the United States: leader of the capitalist, democratic West (the "First World").
• the Soviet Union (USSR): leader of the communist East (the "Second World").

Each tried to spread its system and win allies, dividing much of the world into rival blocs. The flashpoint was a divided Europe, symbolised by the "Iron Curtain" (a phrase Winston Churchill popularised in his 1946 Fulton, Missouri speech) and later by the Berlin Wall (built 1961, fell 1989). The war stayed "Cold" because a direct clash risked mutual nuclear destruction. Instead the two competed through:

• Propaganda and ideology: each side promoting its way of life as superior.
• Espionage: spy agencies like the American CIA and the Soviet KGB.
• An arms race: in nuclear and conventional weapons.
• A space race: the USSR launched Sputnik (1957), the first artificial satellite, and put the first human (Yuri Gagarin) in space in 1961. The US landed the first humans on the Moon (Apollo 11, 1969).
• Proxy wars fought in third countries:
  • the Korean War (1950–53), which split Korea at the 38th parallel.
  • the Vietnam War, where US forces fought communist North Vietnam until withdrawal in 1973 and the fall of Saigon in 1975.
  • Afghanistan (Soviet invasion 1979).

To organise their blocs, the superpowers built rival military alliances:

• NATO (the North Atlantic Treaty Organisation), formed by the US and its allies in 1949. Its core promise is collective defence: an attack on one member is an attack on all.
• the Warsaw Pact, formed by the USSR and Eastern Europe in 1955, in response to West Germany's entry into NATO. It dissolved in 1991.

The US also wove alliances in Asia (such as SEATO and CENTO) to "contain" communism. NATO survived the Cold War and later expanded eastward.

Both sides built huge nuclear stockpiles. This created a balance of terror called deterrence: neither side would attack because the other could destroy it in return. The phrase mutually assured destruction (MAD) captured the logic. A first strike would invite a devastating retaliation, so neither side could "win". The superpowers managed the danger through arms control agreements, which restrain weapons rather than abolish them:

• Limited / Partial Test Ban Treaty (1963): banned nuclear tests in the atmosphere, outer space and under water.
• Nuclear Non-Proliferation Treaty (NPT, 1968): recognises only five nuclear-weapon states (US, USSR/Russia, UK, France, China) and seeks to stop others from acquiring the bomb.
• SALT (Strategic Arms Limitation Talks): beginning with SALT-I in 1972, capping strategic missiles.

Dangerous crises tested the uneasy peace. The earliest was the Berlin Blockade (1948–49), broken by a massive Western airlift. The most serious was the Cuban Missile Crisis of 1962. The USSR under Nikita Khrushchev placed nuclear missiles in communist Cuba, within striking range of the US. President John F. Kennedy ordered a naval "quarantine" (blockade) of Cuba. After a thirteen-day standoff the USSR removed the missiles. The US pledged not to invade Cuba and quietly removed its missiles from Turkey. Such close calls led to a 1970s thaw known as détente.

Many newly independent countries of Asia and Africa refused to join either bloc. The Non-Aligned Movement (NAM) grew out of this impulse. Its founding figures were:

• Jawaharlal Nehru: India.
• Gamal Abdel Nasser: Egypt.
• Josip Broz Tito: Yugoslavia.
• Kwame Nkrumah: Ghana.
• Sukarno: Indonesia.

The Bandung Conference (1955) in Indonesia, an Afro-Asian meeting of newly free nations, was the key forerunner. NAM was formally launched at its first summit in Belgrade in 1961, attended by 25 countries. India hosted the 7th NAM summit in New Delhi (1983).

Non-alignment was not neutrality, isolation or weakness. It was a positive choice to stay independent of both superpowers and judge each issue on its merits. NAM pressed for peace, disarmament, decolonisation and an end to racism. By the 1970s it also demanded a New International Economic Order (NIEO): fairer terms of trade and aid for poorer nations. NAM gave smaller nations a collective voice and helped reduce Cold War tensions.

The Cold War ended not with a battle but with a collapse. By the 1980s the USSR, a federation of 15 republics led from Moscow, was in deep trouble:

• A stagnant planned economy: in a planned economy the state, not the market, decides what to produce. Growth slowed to near zero, consumer goods were scarce, and the USSR fell behind Western technology and living standards.
• The arms race: competing with the US consumed a huge share of national resources and starved the civilian economy.
• The war in Afghanistan: the Soviet army intervened in 1979 and stayed until 1989. The drain on money and morale earned it the label of the Soviet Union's "Vietnam".
• A rigid system: bureaucratic rule without accountability bred corruption and public frustration.

Mikhail Gorbachev became General Secretary of the Communist Party in 1985. He tried to save the system through reform, not abolish it. His two signature reforms are a favourite exam pairing:

• Glasnost: "openness". Loosening censorship and allowing freer speech, debate and criticism of the government.
• Perestroika: "restructuring". Reforming the economy by allowing limited private enterprise and market mechanisms within the socialist system.

The reforms unleashed forces Gorbachev could not control:

• Eastern Europe broke free (1989): the Soviet-aligned communist regimes fell one after another. The Berlin Wall fell in November 1989, the great symbolic moment. Germany was reunified in 1990.
• The republics demanded independence: nationalist movements, especially in the Baltic states (Estonia, Latvia, Lithuania), pushed to leave.
• The August 1991 coup: a failed hardliner coup against Gorbachev discredited the old guard and accelerated the breakup. Boris Yeltsin rose as Russia's leader.

In December 1991 the Soviet Union was formally dissolved into 15 independent countries. Russia became the principal successor state. It took the USSR's seat on the UN Security Council and inherited its nuclear arsenal. Note the two dates students confuse: the Berlin Wall fell in 1989, but the USSR disintegrated in 1991.

The former communist states then had to switch from a planned economy to market capitalism. The dominant method was a rapid, all-at-once approach nicknamed "shock therapy", backed by the World Bank and the International Monetary Fund (IMF). Its core measures:

• Freeing prices: ending state price controls overnight.
• Privatisation: selling off state-owned factories, farms and assets quickly.
• Opening up: removing trade protections and welcoming foreign investment.
• Private agriculture: replacing collective farms.

The results were largely harsh. Whole industries collapsed, and Russian output fell as in a depression. Unemployment and poverty soared while the old safety net vanished. Inflation wiped out savings. State assets were sold cheaply, and a small group of insiders, the oligarchs, grew enormously rich. Critics called it "the largest garage sale in history". The standard exam contrast is China, which reformed step by step and avoided the worst of the collapse.

With its rival gone, the United States became the world's sole superpower. The bipolar Cold War order gave way to a unipolar one with a single dominant power. Western capitalism and liberal democracy spread so widely that some called the moment the "end of history". Eastern European states moved West, and several later joined NATO and the European Union. The end of bipolarity also unleashed conflicts the old balance had kept in check, such as the ethnic wars in the 1990s breakup of Yugoslavia.

Scholars call this dominance hegemony, from the ancient Greek word for the leadership of one state over others. The shift was confirmed at once: in the 1991 Gulf War (Operation Desert Storm), a US-led coalition expelled Iraq from Kuwait under a UN mandate. Hegemony works in three senses, and the US shows all three:

• Hard (military) power: the US accounts for roughly 40% of all military spending in the world, more than the next several spenders combined. The deeper edge is the quality gap: a technological lead in precision weapons, stealth, satellites and command systems. The 9/11 attacks of 2001 brought the "War on Terror": the 2001 invasion of Afghanistan (Operation Enduring Freedom) toppled the Taliban, and the 2003 invasion of Iraq (Operation Iraqi Freedom) removed Saddam Hussein. The Iraq invasion went ahead without explicit UN Security Council backing.
• Structural (economic) power: the US underwrites the structures of the world economy. It provides global "public goods" like the sea lanes that trade depends on, and the internet grew out of a US military research project (ARPANET). It has the largest national economy, American firms dominate technology and finance, and the US dollar is the world's reserve currency: global trade, oil and central-bank reserves are priced and held in dollars. The post-1945 economic order was designed at Bretton Woods (1944) around the IMF and the World Bank, where the US holds the largest voting share and an effective veto over major IMF decisions.
• Soft (cultural) power: a term associated with the scholar Joseph Nye, meaning getting what you want through attraction rather than coercion. Hollywood films, music, fast food, blue jeans, leading universities and the dominance of English make the US way of life look normal and desirable. Soft power can outlast hard power: even critics of US policy consume US culture.

US power, however vast, is not unlimited. Three constraints check it, two from inside the US itself:

• Institutional architecture: the constitutional separation of powers spreads authority across the President, Congress and the courts. Congress controls the budget, which restrains open-ended military adventures.
• An open society: Americans are suspicious of concentrated government power, and the press is free and sceptical. Public opinion can turn against costly interventions, as it did over the long occupations of Iraq and Afghanistan.
• NATO and the market: perhaps the most effective brake. US allies in NATO share its political and economic system, so the US must keep them on side. The US also needs the global market for its own prosperity, making other states partners rather than subjects.

Other nations deal with hegemony through recognised strategies:

• Bandwagoning: extracting benefits by operating within the hegemonic system rather than opposing it, exploiting the opportunities it creates.
• Hiding: staying out of the hegemon's way to avoid attracting its attention.
• Balancing: building rival poles of power, the path of rising states and groupings like BRICS.

The unipolar world did not stay that way. Alternative centres of power have grown to balance US hegemony: groups of nations banding together, and large countries rising fast. The most important are the European Union, ASEAN and China.

After two world wars, the nations of Europe chose to unite step by step:

• Marshall Plan (1948): US aid for rebuilding, alongside the Organisation for European Economic Cooperation (1948).
• Treaty of Rome (1957): set up the European Economic Community.
• Maastricht Treaty (signed 1992, in force 1993): transformed the economic community into the political European Union.

The EU is now a powerful bloc:

• a single market with free movement of goods, services, capital and people.
• a common currency, the euro (introduced for transactions in 1999, as notes and coins in 2002), used by the "eurozone" members.
• shared institutions: the European Parliament, the European Commission, the European Council, the Court of Justice and the European Central Bank.
• its own flag (a circle of twelve gold stars on blue), anthem ("Ode to Joy") and a common foreign and security policy.

It is one of the world's largest economies and the biggest trading bloc, and the euro is a reserve currency that can challenge the dollar. France, an EU member, holds a permanent veto seat on the UN Security Council. Both Britain and France are nuclear powers. But the EU remains a bloc of separate nations. Members differ on foreign policy and defence, and Britain left the EU ("Brexit") in 2020.

The Association of Southeast Asian Nations was founded in 1967 by the Bangkok Declaration. Its five original members were Indonesia, Malaysia, the Philippines, Singapore and Thailand. It grew to ten members, promoting economic growth, peace and regional cooperation. Its distinctive features:

• The "ASEAN Way": informal, non-confrontational consensus-building with strict non-interference in members' internal affairs.
• Vision 2020: the goal of an outward-looking community, built on three pillars: the ASEAN Security Community, the ASEAN Economic Community and the ASEAN Socio-Cultural Community.
• ASEAN Regional Forum (ARF, 1994): the platform for security and political dialogue across the Asia-Pacific.
• ASEAN Free Trade Area (AFTA): lowers trade barriers among members and partners.

ASEAN engages all the major powers. India is a dialogue partner, and ASEAN sits at the heart of India's "Act East" policy.

The most striking new power rose through market reforms, not a sudden windfall:

• 1978 reforms: launched under Deng Xiaoping, with an "open door" policy to attract foreign capital and technology.
• Gradual change: agriculture and industry were privatised in steps, and Special Economic Zones (such as Shenzhen) drew foreign investment.
• WTO entry (2001): cemented China's place as the world's manufacturing hub and one of its largest economies.

China is a permanent, veto-wielding member of the UN Security Council and a recognised nuclear power. It is seen as the most serious long-term challenge to US dominance. For India, China is both a major trading partner and a strategic rival: the border remains unsettled, and both compete for regional influence. Together the EU, ASEAN and China, along with India, a more assertive Russia and groupings like BRICS, are turning the unipolar world into a more multipolar one.
