Detailed Explanation of The End of the Cold War (Edexcel) (1970-1991) ❄️
🌍 The Significance of Détente (1970s)
Détente, meaning ‘relaxation’ in French, refers to the easing of hostility between the USA and the USSR during the early 1970s. This period was marked by treaties like SALT I (Strategic Arms Limitation Talks) which limited nuclear weapons, and agreements on trade and diplomatic contacts. Détente was significant because it reduced the risk of nuclear war, encouraged cooperation in space exploration (e.g., the Apollo-Soyuz mission), and showed both superpowers’ willingness to avoid direct conflict. However, this period of peace was fragile and did not solve the underlying rivalry.
💥 The Impact of the Soviet Invasion of Afghanistan (1979)
The Soviet invasion of Afghanistan in 1979 led to a major setback for détente. The USSR sent troops to support a communist government, which triggered a guerrilla war fought by Afghan rebels supported by the USA and other Western countries. The invasion alarmed the West, leading to boycotts of the 1980 Moscow Olympics and increased military spending. This event damaged relations and ended the warming of the 1970s, marking the start of the Second Cold War.
🚀 The Second Cold War and the Strategic Defense Initiative (SDI)
During the early 1980s, tensions soared again between the superpowers, known as the Second Cold War. One major cause was the USA’s introduction of the Strategic Defense Initiative (SDI), nicknamed “Star Wars,” announced by President Reagan in 1983. SDI was a plan to develop space-based missile defence systems to protect the US from Soviet nuclear attacks. The USSR viewed SDI as a threat because it could undermine the balance of power by giving the USA a defensive advantage. SDI forced the Soviet Union to spend heavily on military technology, worsening their economy while increasing distrust and hostility.
🔄 Gorbachev and the Transformative Policies of Glasnost and Perestroika
Mikhail Gorbachev became Soviet leader in 1985 and realised the USSR needed major reform. He introduced two key policies:
- Glasnost (Openness): This encouraged more freedom of speech, press, and political openness. It allowed criticism of the government and exposed widespread problems in the USSR.
- Perestroika (Restructuring): This was aimed at reforming the Soviet economy by introducing some market-like reforms and reducing state control.
These reforms changed Soviet society deeply. Glasnost encouraged public debate about the failures of communism and government inefficiency, while Perestroika aimed to rebuild the economy to make it more productive. However, these reforms also weakened the Communist Party’s control, led to demands for independence in Soviet republics, and made it difficult to maintain the Soviet union’s power.
⚠️ Key Factors Leading to the Collapse of the Soviet Union
Several factors contributed to the collapse of the Soviet Union in 1991:
- Economic Weakness: The USSR’s economy was struggling due to bad management, heavy military spending (especially due to the arms race and SDI pressure), and inefficient central planning.
- Political Reform and Nationalism: Gorbachev’s reforms allowed nationalist movements in Eastern Europe and Soviet republics to demand independence.
- Loss of Control in Eastern Europe: The fall of communist governments in Eastern Europe (like East Germany, Poland, and Czechoslovakia) weakened Soviet influence.
- Failed Coup of 1991: Hardline communists attempted a coup against Gorbachev but failed, which further discredited the Party and accelerated the USSR’s dissolution.
- Leadership of Gorbachev: His willingness to reduce confrontation with the West and allow political freedoms removed the foundation of Soviet authoritarian control.
By December 1991, the Soviet Union officially dissolved, ending the Cold War era.

✍️ 10 Examination-Style 4-Mark Questions with 6-Sentence Answers on The End of the Cold War
Question 1: What was the significance of détente in the Cold War between 1970 and 1991?
Détente was a period of reduced tensions between the USA and the USSR during the 1970s. It led to important arms control agreements, such as the SALT treaties, which limited nuclear weapons development. Détente allowed both superpowers to communicate more effectively, reducing the risk of direct military conflict. However, it did not end the rivalry but created a more stable environment for negotiations. The policy also encouraged cultural and economic exchanges. In summary, détente helped slow the Cold War competition but did not fully resolve the underlying issues.
Question 2: How did the Soviet invasion of Afghanistan in 1979 affect Cold War relations?
The Soviet invasion of Afghanistan marked the end of détente and the start of a more confrontational phase known as the Second Cold War. The USA saw the invasion as Soviet expansionism and increased support for Afghan guerrillas, the Mujahideen. This led to a boycott of the 1980 Moscow Olympics by the West and a renewed arms race. The invasion drained Soviet resources and morale, contributing to internal problems. It also created a global backlash against the USSR’s aggressive policies. Overall, the invasion worsened East-West relations and intensified the Cold War rivalry.
Question 3: What impact did the Strategic Defense Initiative (SDI) have on the Cold War?
The SDI, also called “Star Wars,” was introduced by US President Ronald Reagan in 1983 as a missile defence system. It aimed to protect the USA from Soviet nuclear attacks using advanced technology, which alarmed the USSR. The Soviets could not afford to compete with this expensive programme, which escalated the arms race. SDI pressured the Soviet economy and contributed to their willingness to negotiate arms reduction later. It also symbolised US technological and military superiority. Therefore, SDI played a key role in shifting the Cold War balance towards the USA.
Question 4: Explain the main goals of Gorbachev’s Glasnost policy.
Glasnost, meaning “openness,” was introduced by Mikhail Gorbachev in the mid-1980s to make the Soviet government more transparent. It allowed greater freedom of speech, press, and political criticism. This policy reduced censorship and encouraged public discussions about government and social issues. Glasnost aimed to increase government accountability and reform Soviet society. However, it also exposed the extent of problems within the USSR, increasing demands for change. Glasnost significantly influenced the loosening of Soviet control and reforms leading to the Cold War’s end.
Question 5: What was Perestroika, and why was it important?
Perestroika means “restructuring” and was Gorbachev’s economic reform policy to revive the Soviet economy. It introduced limited market-like reforms, such as some private ownership and decentralised decision-making. The goal was to improve efficiency and productivity within the communist system. Perestroika faced resistance from hardliners and was not very successful in stopping economic decline. However, it paved the way for political reforms and reduced government control. Perestroika was a crucial step toward the Soviet Union’s transformation and eventual collapse.
Question 6: Why did the Soviet Union collapse in 1991?
The Soviet Union collapses due to a combination of economic, political, and social factors. The slow economy, worsened by costly arms spending and Afghanistan, weakened the country. Gorbachev’s reforms, Glasnost and Perestroika, unintentionally exposed systemic problems and encouraged nationalist movements in Soviet republics. Political freedoms led to demands for independence, which the central government could no longer control. Additionally, failed attempts to preserve the USSR through a coup in 1991 further destabilised the government. The result was the official dissolution of the Soviet Union in December 1991.
Question 7: How did détente influence arms control agreements during the Cold War?
Détente encouraged the USA and USSR to negotiate arms control to reduce the threat of nuclear war. It led to important treaties like SALT I and SALT II, which limited the number of nuclear weapons and missile launchers each side could build. These agreements aimed to prevent an expensive and dangerous arms race. Détente built trust between the superpowers, although it did not eliminate competition. The arms control treaties were a sign of the two sides trying to manage their rivalry more safely. Détente showed that communication was possible even amid Cold War tensions.
Question 8: What role did Gorbachev’s reforms play in ending the Cold War?
Gorbachev’s reforms changed Soviet foreign and domestic policies, reducing Cold War tensions. Glasnost allowed more openness, press criticism, and dialogue with the West. Perestroika sought economic renewal but also reduced government control. Gorbachev improved relations with the USA and agreed to major arms reductions with Reagan. He decided not to use force to maintain control over Eastern Europe, which led to the fall of communist governments there. These reforms helped create the conditions that brought the Cold War to an end.
Question 9: Describe the global reaction to the Soviet invasion of Afghanistan.
The global reaction was mostly negative, especially from the West, who saw the invasion as Soviet aggression. The USA led a boycott of the 1980 Moscow Olympics as a protest. Many countries condemned the USSR at the United Nations. The invasion also encouraged the USA to provide support to Afghan resistance fighters, increasing Cold War tensions. Other communist countries were divided in their support. The invasion isolated the USSR internationally and increased opposition to Soviet policies.
Question 10: What was the Second Cold War, and how did it differ from the earlier period of détente?
The Second Cold War was a period from the late 1970s to the late 1980s marked by renewed hostility between the USA and USSR. It began after the Soviet invasion of Afghanistan and was intensified by Reagan’s hardline policies, including the SDI programme. Unlike détente, which aimed to reduce tensions, this period saw a revival of arms build-up and confrontational rhetoric. Military spending increased significantly on both sides. However, it also set the stage for later negotiations when both sides realised the dangers and costs involved. The Second Cold War was therefore a more tense but short-lived phase before the Cold War ended.
🧠 10 Examination-Style 6-Mark Questions with 10-Sentence Answers on The End of the Cold War
1. Explain the causes and effects of détente during the Cold War period from 1970 to 1991.
Détente was caused by the superpowers’ desire to reduce the risk of nuclear war and ease tensions after decades of hostility. The Cuban Missile Crisis in 1962 highlighted how close nuclear conflict could come, encouraging both the USA and USSR to seek cooperation. Economic issues also pushed détente: the USA needed to reduce its military spending, and the Soviet Union wanted to focus on internal development. Key agreements like SALT I and the Helsinki Accords resulted from détente, slowing the arms race and improving East-West relations. However, détente did not mean complete trust; rivalry and propaganda continued despite diplomatic talks. It helped promote cultural and scientific exchanges between the West and the Soviet bloc. The policy eventually weakened as both sides suspected the other of continuing military build-ups. Détente reduced the immediate threat of nuclear war but did not solve deeper ideological conflicts. By the late 1970s, détente collapsed due to events like the Soviet invasion of Afghanistan. Thus, détente was a cautious step towards peace but limited in its long-term success.
2. Analyse the consequences of the Soviet invasion of Afghanistan on Cold War tensions.
The Soviet invasion of Afghanistan in 1979 was a major blow to détente and worsened Cold War tensions significantly. The invasion was seen by the USA as Soviet aggression extending into the Muslim world, threatening American interests in the Middle East. In response, the USA boycotted the 1980 Moscow Olympics, marking a symbolic protest against Soviet actions. The CIA increased support for Afghan Mujahideen rebels, escalating a proxy war that dragged on for nearly a decade. This conflict became a costly and draining “Vietnam” for the USSR, weakening its economy and military morale. The invasion led to a buildup of US arms and missile programmes, contributing to the Second Cold War. Western powers condemned the Soviet Union at the United Nations, impacting diplomatic relations. The war deepened the ideological divide and sowed distrust between the superpowers. The Soviet defeat in Afghanistan damaged its international reputation and exposed systemic weaknesses. Therefore, the invasion was a pivotal point that reversed progress made during détente.
3. What role did the Strategic Defense Initiative (SDI) play in escalating Cold War tensions in the 1980s?
The Strategic Defense Initiative (SDI), announced by President Reagan in 1983, played a key role in escalating Cold War tensions by challenging the idea of mutual nuclear deterrence. SDI aimed to develop a missile defence system capable of shooting down Soviet ICBMs from space. The Soviet leadership saw this as a threat to the balance of power, fearing it would make their nuclear arsenal obsolete. This perception led to increased Soviet defence spending in an attempt to counter SDI, worsening their economic problems. SDI intensified the arms race as the USSR hurried to develop countermeasures, heightening global fears of renewed conflict. The initiative also undermined existing arms control talks, as the US appeared less committed to disarmament. Critics argued that SDI was technologically unrealistic but politically provocative. It symbolised Reagan’s hardline stance against the USSR and reflected the failure of détente. Despite escalating tensions, SDI pushed the Soviets to seek new diplomatic approaches due to economic strain. Ultimately, SDI contributed to both raised Cold War tensions and the eventual need for arms reductions.
4. Describe the main reforms introduced by Mikhail Gorbachev, focusing on Glasnost and Perestroika.
Gorbachev introduced Glasnost (openness) and Perestroika (restructuring) in the mid-1980s to revive the failing Soviet system. Glasnost allowed greater freedom of speech, the press, and political debate, which was a major change from previous censorship. This openness exposed Soviet citizens to criticism of government policies and history, especially regarding Stalin’s regime. Perestroika aimed to restructure the economy by introducing limited market mechanisms and reducing central planning. It encouraged entrepreneurship and efficiency but stopped short of full capitalism. These reforms were designed to address economic stagnation and improve productivity. Gorbachev also sought to reduce Cold War tensions by promoting arms control negotiations and withdrawing from Afghanistan. However, Glasnost unleashed nationalist and democratic movements in Soviet republics, weakening central control. Perestroika faced resistance from conservatives within the Communist Party, causing political instability. Despite their hopeful aims, these reforms accelerated the collapse of Soviet authority and contributed to the USSR’s breakup.
5. Why did the Soviet Union collapse in 1991?
The Soviet Union collapsed in 1991 due to a combination of economic, political, and social factors. Economically, prolonged stagnation and decline, worsened by costly military spending and the Afghan war, depleted resources. Political reforms under Gorbachev unintentionally weakened Communist control by encouraging open criticism and nationalist movements. Glasnost’s openness led to demands for independence in Soviet republics like the Baltic states. Perestroika reforms failed to stimulate growth and caused shortages, increasing public dissatisfaction. Nationalist tensions, ethnic conflicts, and calls for sovereignty escalated within the USSR. The failed August 1991 coup by hardline Communists further destabilised the government. Internationally, the end of the Cold War reduced the USSR’s global influence and allies. Boris Yeltsin and Russian republic leaders pushed for more autonomy or independence. By December 1991, the Soviet Union formally dissolved, ending decades of Cold War rivalry.
6. How did the policy of détente affect arms control agreements between the USA and the USSR?
Détente led to important arms control agreements like the Strategic Arms Limitation Talks (SALT I) and the Anti-Ballistic Missile (ABM) Treaty in 1972. These agreements aimed to limit the number of nuclear weapons and missile defence systems, reducing the risk of nuclear war. SALT I froze the number of ICBMs and submarine-launched missiles, stabilising the arms race. The ABM Treaty prevented the deployment of comprehensive missile defence systems, maintaining mutually assured destruction (MAD). Détente also paved the way for the Helsinki Accords, which included arms control commitments and improved East-West relations. However, arms control talks often faced challenges as both sides accused each other of cheating. Détente’s success was limited as the superpowers continued to develop new weapons technologies. The invasion of Afghanistan and the arrival of Reagan’s SDI ended the era of arms control détente. Still, the agreements laid groundwork for future treaties like START. Détente showed that arms control could be part of diplomacy, even amid rivalry.
7. Discuss the impact of the Soviet invasion of Afghanistan on the global Cold War context.
The Soviet invasion of Afghanistan in 1979 had a major impact on the global Cold War context by reigniting tensions between East and West. It ended the period of détente, showing the USSR was willing to use force to expand influence. The USA and its allies viewed the invasion as Soviet aggression threatening the Middle East and South Asia. In response, the US led a boycott of the 1980 Moscow Olympics and increased military aid to anti-Soviet fighters in Afghanistan. This support turned Afghanistan into a proxy battleground and prolonged the conflict. The invasion damaged the USSR’s international reputation and isolated it diplomatically. It also caused heightened military spending on both sides, especially with the USA’s Strategic Defense Initiative. Non-aligned countries were alarmed by superpower rivalry expanding into their regions. The Afghan war contributed to Soviet economic decline and unrest at home. Overall, the invasion escalated Cold War conflicts and shifted the struggle into new areas.
8. What were the main goals of Gorbachev’s foreign policy, and how did they influence the end of the Cold War?
Gorbachev’s foreign policy aimed to reduce Cold War tensions, scale back military confrontation, and improve relations with the West. He wanted to end the costly arms race, particularly through negotiations on nuclear arms reduction. Policies such as withdrawing Soviet troops from Afghanistan and supporting arms control treaties showed this commitment. Gorbachev also allowed Eastern European communist governments more independence, leading to the fall of the Berlin Wall and the collapse of Soviet influence in the region. His desire for cooperation rather than confrontation helped to de-escalate global tensions. This approach gained Western support, especially from leaders like Reagan and Thatcher. Gorbachev’s policies demonstrated a shift from old Cold War doctrines to new diplomacy. By promoting glasnost and perestroika at home, he helped open Soviet society and participate openly in global affairs. These actions significantly influenced the peaceful end of the Cold War. Gorbachev’s reforms transformed superpower relations, ending decades of hostility.
9. How did Glasnost contribute to the collapse of the Soviet Union?
Glasnost contributed to the Soviet Union’s collapse by encouraging freedom of expression and open criticism of the government and Communist Party. This openness exposed governmental corruption, economic failures, and historical mistakes, reducing public trust. Media and citizens began to demand political reforms and transparency, breaking the tradition of censorship. Nationalist groups and ethnic minorities used Glasnost to push for greater autonomy and independence from Moscow. Discussion of previously banned topics, including Stalin’s purges, eroded the legitimacy of the Communist Party. The policy unleashed political movements and protests that were hard to control. Glasnost weakened central authority by encouraging debate and opposition, undermining the Communist regime. It also emboldened reformers and critics within the party to challenge hardliners. Although intended to strengthen socialism, Glasnost hastened demands for change and reform. Ultimately, this openness helped lead to the Soviet Union’s political disintegration.
10. Outline the key reasons behind the failure of Perestroika.
Perestroika failed because it was an incomplete and inconsistent attempt to reform the Soviet economy without fully abandoning central planning. Introducing limited market mechanisms created confusion and resistance from entrenched bureaucrats and party officials. Many state enterprises lacked experience with competition and struggled with inefficiency. Economic problems worsened as shortages and inflation increased, leading to public dissatisfaction. The reforms did not address the deep structural issues such as poor productivity and outdated technology. Political instability from Glasnost undermined economic progress as unrest and calls for independence spread. Perestroika’s gradual approach alienated both hardliners who wanted to maintain control and reformers who demanded faster change. The economy declined further during the reform period, causing a loss of faith in the Communist Party. Additionally, external pressures like the arms race strained government resources. Overall, Perestroika’s half measures deepened the crisis and accelerated the Soviet collapse.
