The Cold War and the New World Order – NDA History Notes

When World War II ended in 1945, the world expected peace. Instead, it got a different kind of conflict, one fought not with battles but with ideology, espionage, proxy wars, and the constant fear of nuclear annihilation. This conflict was called the Cold War.

The Cold War was a confrontation between two superpowers: the United States of America and the Union of Soviet Socialist Republics (USSR). The USA stood for capitalism and liberal democracy. The USSR stood for communism and one-party rule. Neither side could attack the other directly without risking nuclear war. So they competed everywhere else: in Europe, Asia, Africa, Latin America, and even in space.

The Cold War lasted from roughly 1947 to 1991, when the USSR collapsed. It shaped every major event in world politics for nearly half a century. It determined which countries received aid, which governments were supported or overthrown, and which wars were fought.

For NDA, three facts from this chapter have been tested: the Suez Crisis of 1956 [NDA 2019-II], the Non-Aligned Movement and its founding leaders — particularly Kwame Nkrumah of Ghana [NDA 2022-I], and Nelson Mandela’s role in ending apartheid in South Africa [NDA 2014-I].

1. How the Cold War Began

The USA and USSR had been allies during World War II. They shared one goal: defeating Nazi Germany. Once that goal was achieved, every difference between them resurfaced. Those differences were enormous.

The USA was the world’s largest capitalist economy. It believed in private property, free markets, and democratic elections. The USSR was the world’s first communist state. It believed in state ownership of the economy, one-party rule, and the eventual global spread of communism. These two systems were ideologically incompatible.

After WWII, Soviet forces occupied most of Eastern Europe. Instead of withdrawing, the USSR helped install communist governments in Poland, Czechoslovakia, Hungary, Romania, Bulgaria, and East Germany. Western leaders saw this as Soviet expansion. The USSR saw it as necessary protection against another invasion from the west.

By 1947, the wartime alliance had completely broken down. The Cold War had begun.

Britain’s Prime Minister Winston Churchill described an “Iron Curtain” dividing Europe (1946) — the division between Soviet-controlled Eastern Europe and the free Western democracies. The term Cold War refers to a conflict without direct military engagement between the two superpowers. NOT a war with direct battles between the USA and USSR — fought through alliances, aid, ideology, and proxy conflicts.

2. Key Doctrines and Alliances

The USA responded to Soviet expansion with a strategy called Containment — the goal of preventing communism from spreading further.

In 1947, US President Harry Truman announced the Truman Doctrine — the USA would support any free people resisting communist takeover. He requested military and economic aid for Greece and Turkey, both facing communist pressure.

In the same year, the USA launched the Marshall Plan — a massive programme of economic aid to rebuild war-damaged Western Europe. The USA gave approximately $13 billion to rebuild Western European economies. A prosperous Western Europe, the Americans believed, would resist communism.

In 1949, the Western powers formed the North Atlantic Treaty Organisation (NATO) — a military alliance in which an attack on any member would be treated as an attack on all.

The USSR responded in 1955 with the Warsaw Pact — a military alliance of communist states in Eastern Europe.

Organisation	Year	Members	Purpose
NATO	1949	USA, Britain, France, West Germany and others	Western military alliance against USSR
Warsaw Pact	1955	USSR, East Germany, Poland, Hungary and others	Soviet military alliance against NATO
Marshall Plan	1947	Western Europe (recipients)	US economic aid to rebuild Europe

3. The Berlin Crises

Berlin became the sharpest point of Cold War tension. The city lay deep inside Soviet-controlled East Germany but was divided into four zones: American, British, French, and Soviet.

In 1948, the USSR blockaded all road and rail links to West Berlin, trying to force the Western powers out. The USA and Britain responded with the Berlin Airlift — flying supplies into West Berlin for nearly a year. The USSR lifted the blockade in May 1949. The West had won the first Berlin crisis.

In 1961, the second crisis arrived. Millions of East Germans were fleeing to West Berlin to escape communist rule. The East German government, with Soviet backing, built the Berlin Wall overnight on 13 August 1961. The Wall divided the city for 28 years.

The Berlin Wall fell on 9 November 1989 — a defining moment in the end of the Cold War.

4. The Cuban Missile Crisis — 1962

The Cuban Missile Crisis was the most dangerous moment of the Cold War, the point at which nuclear war came closest.

In 1959, a communist revolution in Cuba brought Fidel Castro to power. Cuba is 145 kilometres from the coast of Florida. In 1962, American spy planes discovered that the USSR was installing nuclear missiles in Cuba, missiles capable of hitting most of the USA within minutes.

US President John F. Kennedy demanded that the USSR remove the missiles and ordered a naval blockade of Cuba. For 13 days (October 1962), the world held its breath. Soviet ships carrying more missiles were sailing toward Cuba. If they crossed the American blockade, war could begin.

At the last moment, Soviet leader Nikita Khrushchev agreed to remove the missiles. In return, the USA quietly agreed not to invade Cuba and to remove its own missiles from Turkey. As an immediate result, a direct telephone hotline was established between Washington and Moscow to prevent future crises.

5. The Suez Crisis — 1956

★ IMPORTANT The Suez Crisis is directly NDA-tested [NDA 2019-II]. The key trap is assuming Britain and France succeeded. They did not. In 1956, Egyptian President Gamal Abdel Nasser nationalised the Suez Canal — which had been owned by a British-French company. Britain, France, and Israel launched a military attack on Egypt to take back control. Both the USA and the USSR condemned the attack and pressured the attackers to withdraw. Faced with this pressure from both superpowers, Britain, France, and Israel were forced to withdraw in humiliation. The Suez Crisis marked the effective end of British and French power as independent global actors. NOT a victory for Britain or France. They attacked and were forced to retreat. [NDA 2019-II]

The Suez Crisis confirmed that the USA and USSR were the only true superpowers. Any action by a smaller power, even a former great power like Britain, required superpower approval or would be reversed by superpower pressure.

6. The Non-Aligned Movement

Not every country wanted to take sides in the Cold War. Many newly independent nations of Asia and Africa saw the superpower rivalry as a continuation of imperialism, just with different masters. They chose a third path: non-alignment.

The Non-Aligned Movement (NAM) was formally established at the Belgrade Conference in 1961. It brought together nations that refused to join either NATO or the Warsaw Pact.

Five leaders are identified as the founders of the Non-Aligned Movement:

Leader	Country	Role
Jawaharlal Nehru	India	Co-founder; articulated non-alignment philosophy
Gamal Abdel Nasser	Egypt	Co-founder; led Arab nationalism
Kwame Nkrumah	Ghana	Co-founder; leader of pan-Africanism [NDA 2022-I]
Josip Broz Tito	Yugoslavia	Co-founder; independent communist outside Soviet bloc
Sukarno	Indonesia	Co-founder; led Indonesian independence

Kwame Nkrumah was the leader of Ghana — the first sub-Saharan African country to gain independence from colonial rule (1957). He was one of the five core founding figures of the Non-Aligned Movement. [NDA 2022-I]

NOT Nkrumah was from Nigeria or any other country. Nkrumah = Ghana. [NDA 2022-I] The most common error is placing Nkrumah in Nigeria, the largest and most prominent sub-Saharan African country, when Ghana was the first to gain independence and Nkrumah was its leader.

The philosophical foundation for NAM was laid at the Bandung Conference (1955) in Indonesia, where 29 Asian and African nations met. Nehru, Nasser, and Sukarno were key figures there. However, the Non-Aligned Movement was formally founded at the Belgrade Conference in 1961 — NOT at Bandung. Bandung = groundwork (1955). Belgrade = formal founding (1961).

NAM was NOT a neutral movement. NAM countries took strong positions, against colonialism, against apartheid, for disarmament. They simply refused to join either the American or Soviet military bloc. Non-alignment meant active independent foreign policy, not passive fence-sitting.

Memory device — “Nehru Never Tires, Sukarno Nods” — Nehru (India), Nasser (Egypt), Tito (Yugoslavia), Sukarno (Indonesia), Nkrumah (Ghana). Three N’s — Nehru, Nasser, Nkrumah.

7. Proxy Wars — Korea and Vietnam

The Cold War produced many proxy wars — conflicts where the USA and USSR supported opposing sides without fighting each other directly.

Korean War (1950–1953) — After WWII, Korea was divided at the 38th parallel. North Korea (communist, Soviet-backed) invaded South Korea (US-backed) in 1950. The USA led a UN force to defend South Korea. China entered on North Korea’s side. The war ended in an armistice (1953) with Korea still divided at roughly the same line, where it remains today.

Vietnam War (1955–1975) — Vietnam was divided between communist North Vietnam and US-backed South Vietnam. The USA sent troops to prevent a communist victory. Despite enormous military superiority, the USA could not win. American troops withdrew in 1973. North Vietnam unified the country under communism in 1975. Vietnam was a major defeat for US foreign policy and shook American confidence deeply.

Conflict	Period	Outcome
Korean War	1950–1953	Armistice; Korea remains divided today
Vietnam War	1955–1975	US withdrawal; communist North Vietnam unified the country
Cuban Revolution	1959	Communist Cuba 145 km from USA — triggered missile crisis

8. The Arms Race and Space Race

The Cold War was also a competition in technology and military power.

The Arms Race began when the USSR tested its first atomic bomb in 1949 — four years after the USA. Both sides then built hydrogen bombs, intercontinental missiles, and nuclear submarines. By the 1960s, both superpowers had enough nuclear weapons to destroy the world many times over. This situation was called MAD — Mutually Assured Destruction. Neither side could attack without being destroyed in return.

The Space Race began when the USSR launched Sputnik — the world’s first artificial satellite — on 4 October 1957. This shocked the USA. The USSR then sent the first human into space: Yuri Gagarin (12 April 1961). The USA responded with the Apollo programme. Neil Armstrong became the first human to walk on the Moon on 20 July 1969. The USA had won the Space Race.

Space Race sequence — Sputnik Spins, Gagarin Goes, Armstrong Arrives: – Sputnik — first satellite (USSR, 4 October 1957) – Yuri Gagarin — first human in space (USSR, 12 April 1961) – Neil Armstrong — first human on Moon (USA, 20 July 1969)

USSR led early. USA won the final prize.

9. South Africa and the End of Apartheid

South Africa operated a system of racial segregation called apartheid (an Afrikaans word meaning “separateness”). Under apartheid, the white minority government denied basic rights to the Black majority and other non-white groups. Apartheid was enforced through brutal laws. People were classified by race, forced to live in separate areas, banned from certain jobs, and denied the right to vote.

Nelson Mandela was the leader of the African National Congress (ANC), the main organisation fighting apartheid. In 1964, he was convicted of sabotage and sentenced to life imprisonment. He spent 27 years in prison on Robben Island.

International pressure, economic sanctions, and internal resistance eventually forced the white minority government to negotiate. Mandela was released in 1990. Apartheid was dismantled. In 1994, South Africa held its first fully democratic elections. Nelson Mandela became the first democratically elected President of South Africa. He served from 1994 to 1999. [NDA 2014-I]

Three numbers to remember for Mandela — 27 years in prison; 1994 first democratic election and elected President; 1999 end of his presidency.

NOT imprisoned for terrorism. Mandela was convicted of sabotage — acts of resistance against the apartheid state, not attacks on civilians. He consistently opposed targeting civilians.

NOT Mandela served as president until 2004. He served 1994–1999 — one term only. [NDA 2014-I]

10. The End of the Cold War

By the 1980s, the USSR was struggling. Its economy was stagnant. The war in Afghanistan (1979–1989) had drained resources and morale, described as the Soviet Union’s Vietnam. The communist system was failing to deliver the prosperity it had promised.

Soviet leader Mikhail Gorbachev introduced two reform programmes: Glasnost (openness — freedom of speech and press) and Perestroika (restructuring — economic reform). These reforms unleashed forces that Gorbachev could not control.

In 1989, communist governments across Eastern Europe collapsed one by one: Poland, Hungary, Czechoslovakia, Romania, East Germany. The Berlin Wall fell on 9 November 1989. Germany was reunified in 1990.

On 25 December 1991, the USSR formally dissolved. Fifteen independent republics emerged, the largest being the Russian Federation. The Cold War was over.

11. The New World Order

After 1991, the USA was the world’s only superpower, a situation described as a unipolar world. US President George H.W. Bush used the phrase “New World Order” to describe this moment.

The post-Cold War world was not peaceful. New conflicts emerged: the Gulf War (1991), wars in Yugoslavia, genocide in Rwanda (1994), the September 11 attacks (2001), and the wars in Afghanistan and Iraq. The world shifted from a bipolar (two-superpower) structure to a more complex, multipolar one as China, India, and other powers grew in influence.

Organisations like the World Trade Organisation (WTO), BRICS, G20, and SCO reflect the emergence of new centres of global power. The end of the Cold War in 1991 directly triggered India’s economic reforms — the USSR’s collapse forced the liberalisation reforms of 1991 under Prime Minister Narasimha Rao and Finance Minister Manmohan Singh.
