What this dot point is asking
NESA expects you to explain how Gorbachev's accession in 1985 and his policies of perestroika, glasnost, and New Thinking ended the Cold War's confrontational dynamic by 1989, through arms control, withdrawal from Afghanistan, the renunciation of the Brezhnev Doctrine, and the bilateral relationship with Reagan and George H.W. Bush.
The answer
The Soviet inheritance
By the early 1980s the Soviet system was in deep stagnation (zastoi). Annual growth had fallen from 5 per cent in the 1960s to about 2 per cent in the 1970s and below 2 per cent in the early 1980s. Oil and gas (now generating 60 per cent of export earnings) made the economy hostage to commodity prices; the 1986 collapse of oil to about $10 per barrel removed the rentier cushion. Military spending consumed an estimated 15 to 20 per cent of GDP. The Afghan war (since December 1979) cost about 15,000 Soviet lives and approximately $50 billion. The CPSU leadership had aged: Brezhnev died on 10 November 1982, Andropov on 9 February 1984, Chernenko on 10 March 1985.
Mikhail Gorbachev was elected General Secretary on 11 March 1985, aged 54, the first Soviet leader born after the revolution. His mentor was Yuri Andropov.
Perestroika and uskorenie
The April 1985 Plenum launched uskorenie (acceleration), an attempt to revive growth through investment in machine-building. The 27th Party Congress (25 February to 6 March 1986) introduced perestroika (restructuring) as a broader programme.
Key measures: the Law on State Enterprises (June 1987) gave enterprises autonomy and the right to retain profits (and the obligation to bear losses, in principle). The Law on Cooperatives (May 1988) legalised private and cooperative enterprise in trade, services, and small manufacturing. The Law on Joint Ventures (January 1987) permitted foreign investment.
The measures failed in practice. Half-marketisation produced inflation, shortages, and queues. State enterprise managers had autonomy without market discipline. The fiscal balance collapsed; the budget deficit reached 11 per cent of GDP by 1991.
Anti-alcohol campaign (May 1985): cut consumption (and tax revenue) without ending the underlying social problem. Estimated revenue loss 1985 to 1987 was about 67 billion roubles.
Glasnost
Glasnost (openness) was less a policy than a permission. Pravda and Ogonyok published criticism of past leaders; Doctor Zhivago (1988), The Children of the Arbat (1987), and Gulag Archipelago (1989) were finally published. The Chernobyl disaster (26 April 1986) tested and broke the culture of secrecy when initial denials gave way under foreign and domestic pressure to disclosure.
Andrei Sakharov was recalled from internal exile in Gorky in December 1986. The Memorial society (1987 to 1988) began documenting Stalinist victims. The 1988 Nagorno-Karabakh conflict and the 1989 Tbilisi massacre (9 April) revealed nationalist mobilisation glasnost had unleashed.
New Thinking
New Thinking (novoye myshlenie) was articulated by Gorbachev's 1987 book Perestroika and operationalised by Foreign Minister Eduard Shevardnadze (replaced Andrei Gromyko, July 1985) and Politburo adviser Aleksandr Yakovlev. Core ideas: nuclear weapons made class war between systems impossible; security must be mutual; Europe was "our common European home" (Strasbourg, 6 July 1989); intervention in other socialist countries was no longer legitimate.
The 28th Party Congress (1990) and Gorbachev's 7 December 1988 UN speech announced unilateral conventional cuts of 500,000 personnel and 10,000 tanks and the renunciation of force in international relations.
Afghan withdrawal: agreed at Geneva on 14 April 1988, completed on 15 February 1989. Total Soviet casualties were about 15,000 dead and 35,000 wounded.
The summits and arms control
Reagan and Gorbachev met four times.
Geneva, 19 to 21 November 1985: no agreement but personal rapport; joint statement that "a nuclear war cannot be won and must never be fought."
Reykjavik, 11 to 12 October 1986: Reagan and Gorbachev came within reach of eliminating all ballistic missiles by 1996. The deal collapsed over Reagan's refusal to confine the Strategic Defence Initiative (SDI, "Star Wars") to the laboratory.
Washington, 8 to 10 December 1987: the Intermediate-range Nuclear Forces Treaty (INF Treaty) was signed by Reagan and Gorbachev on 8 December 1987. The treaty eliminated all nuclear and conventional ground-launched ballistic and cruise missiles with ranges between 500 and 5,500 kilometres. By the May 1991 deadline, the United States eliminated 846 missiles (Pershing II, ground-launched cruise) and the USSR 1,846 (SS-20, SS-4, SS-5, SS-12, SS-23). On-site verification was unprecedented. The first nuclear arms reduction treaty.
Moscow, 29 May to 3 June 1988: ratification exchange, Reagan's Spaso House speech rejecting the "evil empire" label; "that was another time, another era."
The Sinatra Doctrine
The Brezhnev Doctrine (Pravda, 26 September 1968) had asserted Soviet right to intervene in any socialist country threatening "the foundations of socialism." Gorbachev replaced it with what Foreign Ministry spokesman Gennady Gerasimov dubbed (October 1989) the "Sinatra Doctrine": Eastern European states could do it "my way."
The doctrine was tested and confirmed by the Hungarian opening of the Austrian border (10 September 1989), the Polish round-table elections (June 1989), and the fall of the Berlin Wall (9 November 1989). Soviet troops did not move.
Bush and the soft handover
George H.W. Bush succeeded Reagan on 20 January 1989. After a strategic pause and review, Bush met Gorbachev at Malta (2 to 3 December 1989), days after the Wall fell, and announced (in Gorbachev's words) that the Cold War was over. The strategic relationship moved on to German unification (Two Plus Four Treaty, 12 September 1990), the START I Treaty (31 July 1991), and the Soviet acceptance of Operation Desert Storm (17 January 1991).

Historiography
Robert Service's biography Gorbachev (2009) and Archie Brown's The Gorbachev Factor (1996) are standard. Vladislav Zubok's A Failed Empire (2007) and Collapse (2021) cover Soviet decline. John Lewis Gaddis's The Cold War (2005) treats Gorbachev as decisive but constrained. Stephen Kotkin's Armageddon Averted (2001) argues the Soviet collapse was uncoerced and that Reagan was peripheral.
The central debate is agency versus structure. Archie Brown makes Gorbachev's individual choices decisive; Vladislav Zubok stresses that long-run structural rot (commodity dependence, ideological exhaustion) doomed the system whoever led it. John Lewis Gaddis splits the difference - Gorbachev as decisive but constrained by Western pressure - while Stephen Kotkin treats the collapse as uncoerced and Reagan as peripheral. A strong answer stages this as a clash, then judges that decline made an end likely but Gorbachev's restraint made it peaceful.
In one sentence
Gorbachev's reforms (perestroika and glasnost, from April 1985), his New Thinking foreign policy, the Reykjavik (October 1986) and Washington (December 1987) summits producing the INF Treaty, the renunciation of the Brezhnev Doctrine (Sinatra Doctrine, October 1989), and the Afghan withdrawal (February 1989) ended the Cold War's confrontational logic by 1989 by replacing class struggle with common security, even though Gorbachev intended to reform the Soviet system, not to dissolve it.
Examples in context
Example 1. Gorbachev's UN speech (7 December 1988). Gorbachev announced unilateral cuts of 500,000 troops and 10,000 tanks and renounced the "use or threat of force" in international affairs. The speech effectively abandoned the Brezhnev Doctrine. Archie Brown (The Gorbachev Factor, 1996) and William Taubman (Gorbachev: His Life and Times, 2017) treat the speech as the decisive ideological turning point. Robert English (Russia and the Idea of the West, 2000) traces the New Thinking back to reformist intellectuals in IMEMO during the 1970s.
Example 2. The Reykjavik Summit (11 to 12 October 1986) and INF Treaty. Reagan and Gorbachev came within reach of eliminating all nuclear weapons before disagreement on SDI ended the talks. The INF Treaty (8 December 1987) followed, eliminating an entire class of missiles. Melvyn Leffler (For the Soul of Mankind, 2007) frames Reykjavik as the bilateral moral conversation that produced trust. Mary Sarotte (Not One Inch, 2021) draws on the records to show how the personal relationship became institutional.

Practice (NESA)15 marksEvaluate the role of Gorbachev in ending the Cold War.Show worked answer →
A 15-mark "evaluate role" needs a judgement on agency.
- Thesis
- Gorbachev's role was decisive. The structural pressures (economic stagnation, the Reagan build-up, Afghanistan, the youth and intelligentsia's demands) created the opportunity; Gorbachev's choices turned the opportunity into a peaceful end to the Cold War.
- Domestic reform
- Gorbachev became General Secretary on 11 March 1985 after the deaths of Brezhnev (1982), Andropov (1984), and Chernenko (1985). Perestroika (restructuring) was launched at the April 1985 Plenum; uskorenie (acceleration) at the 27th Party Congress (February to March 1986); glasnost (openness) accelerated after Chernobyl (26 April 1986). The 19th Party Conference (June to July 1988) approved political reform with multi-candidate elections to a Congress of People's Deputies (March 1989).
- New Thinking
- Foreign Minister Eduard Shevardnadze (replacing Gromyko, July 1985) and Politburo adviser Aleksandr Yakovlev articulated a foreign policy based on common European home and universal human values rather than class struggle. The withdrawal from Afghanistan (15 February 1989) and the acceptance of the East European revolutions (1989) implemented the doctrine.
- The summits
- Reagan and Gorbachev met at Geneva (November 1985), Reykjavik (October 1986), Washington (December 1987 with the INF Treaty), and Moscow (May to June 1988). The INF Treaty eliminated an entire class of nuclear weapons (846 American and 1,846 Soviet).
- Judgement
- Gorbachev did not intend to end the Soviet system or the Cold War. He intended to reform both. His refusal to use force in 1989, the renunciation of the Brezhnev Doctrine, and the consent to German unification on Western terms ended the Cold War despite his intent.
Practice questions
Original practice questions graded from foundation to exam level, each with a full worked solution. Try them before revealing the solution.
foundation3 marksOutline the difference between glasnost and perestroika.Show worked solution →
A 3-mark "outline" wants the two policies defined and distinguished, with an example each.
- Glasnost (openness)
- Relaxation of censorship and freer public debate from 1986; example - the disclosures forced by Chernobyl (26 April 1986) and the publication of previously banned works such as Gulag Archipelago (1989).
- Perestroika (restructuring)
- Reform of the planned economy; example - the Law on Cooperatives (May 1988) legalising small private enterprise.
- The key contrast
- Glasnost was political and cultural and succeeded in opening debate; perestroika was economic and failed, producing shortages and a ballooning deficit.
- Marking criteria
- 1 mark for defining glasnost with an example; 1 mark for defining perestroika with an example; 1 mark for a clear contrast (political openness vs economic restructuring).
foundation4 marksExplain the significance of the INF Treaty (8 December 1987) in ending the Cold War.Show worked solution →
A 4-mark "explain the significance" needs the treaty's content plus its wider effect.
- What it did
- Signed in Washington on 8 December 1987 by Reagan and Gorbachev, the INF Treaty eliminated all ground-launched ballistic and cruise missiles of 500 to 5,500 km range: 846 American and 1,846 Soviet missiles.
- Why it mattered
- It was the first treaty to abolish an entire class of nuclear weapons (not merely cap growth, as SALT had), and its intrusive on-site verification built unprecedented trust.
- The link to the end
- It converted the near-miss of Reykjavik (October 1986) into a concrete breakthrough and signalled that the arms race - the central confrontation of the Cold War - was being wound down by agreement.
- Marking criteria
- 1 mark for the date/content; 1 mark for "first to eliminate a class"; 1 mark for verification/trust; 1 mark for linking it to the easing of confrontation.
core5 marksSource A (paraphrased, owned): In December 1988 Gorbachev told the United Nations that the Soviet Union would cut 500,000 troops and 10,000 tanks unilaterally, and that "freedom of choice" was a universal principle that admitted no exceptions for any country.
Using Source A and your own knowledge, explain how Gorbachev's New Thinking changed Soviet foreign policy. [5 marks]
Show worked solution →
A 5-mark "explain ... using the source" wants the source decoded, then anchored in own knowledge.
- Decode the source
- The UN speech of 7 December 1988 announced deep unilateral conventional cuts and, in declaring "freedom of choice" universal, signalled that Moscow would no longer enforce socialism in Eastern Europe - the practical death of the Brezhnev Doctrine.
- New Thinking (own knowledge)
- Articulated by Gorbachev's 1987 book Perestroika and driven by Foreign Minister Shevardnadze and adviser Yakovlev, novoye myshlenie held that nuclear weapons made class war between systems suicidal and that security had to be mutual ("our common European home").
- What it produced
- The INF Treaty (December 1987), the Afghan withdrawal (completed 15 February 1989), and the refusal to intervene as Eastern Europe broke away in 1989 (the Sinatra Doctrine, October 1989).
- Marking criteria
- 1 mark for reading the speech as abandoning the Brezhnev Doctrine; 1 to 2 marks for defining New Thinking with Shevardnadze/Yakovlev; 1 mark for naming concrete outcomes (INF, Afghanistan, 1989); 1 mark for the link to ending confrontation.
core5 marksSource B (paraphrased, owned): A historian argues that the collapse of the Soviet system was essentially uncoerced - that Western military pressure was marginal, and that what mattered was Gorbachev's own decision to stop using force to hold the system together.
Using Source B and your own knowledge, assess the usefulness of this interpretation for understanding the end of the Cold War. [5 marks]
Show worked solution →
A 5-mark "assess the usefulness" rewards perspective plus own knowledge, ending in a judgement.
- Perspective
- Source B states the Kotkin position (Armageddon Averted, 2001): the collapse was uncoerced and Reagan was peripheral. It is useful for correcting the triumphalist "Reagan won the Cold War" narrative.
- Corroboration
- It fits much of the record: the USSR was undone by zastoi (stagnation), the 1986 oil-price collapse, and a budget deficit reaching 11 per cent of GDP - not by bankruptcy through the arms race; and Gorbachev's refusal to use force in 1989 was decisive.
- Limitation
- By stressing Gorbachev's choices it can understate the structural pressures (commodity dependence, ideological exhaustion) that constrained him, and the Reagan build-up that raised the cost of competition - factors Gaddis and Service weigh more heavily.
- Judgement
- Highly useful for puncturing the triumphalist myth and foregrounding agency, but it must be read alongside the structural account: Gorbachev chose, but stagnation framed the choice.
- Marking criteria
- 1 mark for naming the uncoerced/Kotkin perspective; 1 to 2 marks for own-knowledge corroboration (stagnation, oil, deficit); 1 mark for a limitation; 1 mark for a judgement on usefulness.
exam25 marksEvaluate the extent to which Gorbachev's reforms, rather than long-term structural decline, brought about the end of the Cold War.Show worked solution →
This is an extended-response/essay. Markers reward a sustained, evidence-based argument that addresses the comparison directly and weaves in historiography - not a narrative.
Band-6 PLAN
- Thesis. Structural decline created the crisis, but Gorbachev's reforms and his refusal to use force converted a crisis into the peaceful end of the Cold War: agency was decisive within limits set by structure. The opportunity was inherited; the outcome was chosen.
- Argument 1 - Structural decline (the enabling condition). Zastoi cut growth below 2 per cent; oil and gas were 60 per cent of exports and the 1986 oil collapse (to about $10 a barrel) removed the cushion; military spending ran at 15 to 20 per cent of GDP; the Afghan war cost about 15,000 lives. The system was failing before Gorbachev. Evidence: the deficit reached 11 per cent of GDP by 1991.
- Argument 2 - Gorbachev's reforms (the active cause). Perestroika, glasnost and uskorenie (from 1985) and New Thinking abroad changed Soviet conduct: the INF Treaty (December 1987), the UN speech (December 1988), the Afghan withdrawal (February 1989). Crucially, glasnost destroyed the regime's legitimacy while perestroika failed to deliver, deepening the crisis even as it transformed foreign policy.
- Argument 3 - The decisive choice: not using force. The renunciation of the Brezhnev Doctrine (Sinatra Doctrine, October 1989) meant the 1989 revolutions met no tanks, unlike 1956 and 1968. This was a choice, not a structural inevitability - a hardliner could have intervened.
- Historiography. Archie Brown (The Gorbachev Factor, 1996) makes individual agency decisive. Stephen Kotkin (Armageddon Averted, 2001) treats the collapse as uncoerced but stresses structural hollowness over personality. John Lewis Gaddis (The Cold War, 2005) sees Gorbachev as decisive but constrained by Western pressure; Vladislav Zubok (A Failed Empire, 2007) emphasises long-run structural failure.
- Judgement. Weigh Brown's agency against Zubok's structure: decline made an end likely, but Gorbachev's reforms and above all his refusal to use force made it peaceful and made it now. Agency was decisive within structural limits.
MODEL PARAGRAPH (Argument 3)
The single most decisive factor was not the depth of Soviet decline but Gorbachev's choice not to defend the empire by force. When Eastern Europe rose in 1989, the Red Army had crushed comparable challenges in Hungary (1956) and Czechoslovakia (1968); the machinery and the precedent for intervention both existed. Instead, the UN speech of December 1988 had renounced the use of force, and in October 1989 spokesman Gennady Gerasimov dubbed the new line the "Sinatra Doctrine" - the satellites could do it "their way." When the Berlin Wall fell on 9 November 1989, Soviet troops stayed in barracks. As Archie Brown argues in The Gorbachev Factor, this was the exercise of individual agency, not the playing-out of an impersonal structural script: a Romanov or a Ligachev might have chosen the tanks. Structural decline made some kind of reckoning likely; Gorbachev's restraint determined that the reckoning was peaceful and that it came in 1989 rather than in some later, bloodier crisis.
Marker's note. A band-6 response keeps "to what extent" in view throughout - ranking reforms and restraint against structural decline rather than narrating Gorbachev's career - anchors every claim in dated evidence, sets at least two historians in genuine tension (Brown's agency vs Zubok's structure), and reaches a graded judgement. Narrating the reforms without weighing agency against structure caps the response in the middle bands.
exam25 marksAssess the view that Gorbachev's reforms succeeded in foreign policy but failed at home.Show worked solution →
This is an extended-response/essay. Markers reward a sustained, evidence-based argument that addresses the proposition directly and weaves in historiography - not a narrative.
Band-6 PLAN
- Thesis. The proposition is largely sound but too neat: Gorbachev's foreign policy achieved its declared aims (ending the arms race and the confrontation) while his domestic programme failed economically and fatally undermined the regime - yet the two were linked, because the same opening that won applause abroad destroyed authority at home.
- Argument 1 - Foreign-policy success. The INF Treaty (December 1987) scrapped a whole class of weapons; the UN speech (December 1988) cut forces unilaterally; the Afghan withdrawal (February 1989) ended a losing war; Malta (December 1989) declared the Cold War over. By his own criteria - mutual security, an end to confrontation - this succeeded.
- Argument 2 - Domestic failure. Perestroika produced half-marketisation without market discipline: inflation, shortages and queues, with the deficit reaching 11 per cent of GDP by 1991. The anti-alcohol campaign (1985) lost about 67 billion roubles in revenue. Uskorenie failed to revive growth.
- Argument 3 - The link and the qualification. Glasnost "succeeded" as openness but in doing so delegitimised the regime - the Chernobyl cover-up exposed, Sakharov recalled (December 1986), nationalist mobilisation unleashed (Nagorno-Karabakh 1988, Tbilisi 1989). So the "success/failure" split understates how foreign triumph and domestic collapse were the same process: a system that could no longer compel obedience.
- Historiography. Archie Brown (1996) credits Gorbachev's reforming agency; Vladislav Zubok (A Failed Empire, 2007) stresses that structural rot doomed the domestic project; Robert Service (Gorbachev, 2009) presents a reformer overtaken by forces he had released; Stephen Kotkin (2001) sees the collapse as uncoerced.
- Judgement. The view holds: triumph abroad, failure at home - but the sharper truth is that the domestic failure and the foreign success shared one cause, the deliberate loosening of coercion that Gorbachev could start but not control.
MODEL PARAGRAPH (Argument 2)
At home, Gorbachev's economic reforms failed on their own terms. Perestroika dismantled elements of central planning without building a functioning market: the Law on State Enterprises (1987) granted managers autonomy but not the discipline of competition, so factories raised wages and prices without raising output. The result was inflation, empty shelves and lengthening queues, while the budget deficit climbed towards 11 per cent of GDP by 1991. Even the well-meant anti-alcohol campaign of 1985 backfired, stripping roughly 67 billion roubles of tax revenue from the state it was meant to strengthen. As Vladislav Zubok argues in A Failed Empire, the economic project was undermined less by sabotage than by the structural impossibility of half-reforming a command economy; Robert Service portrays a leader steadily overtaken by the consequences of his own openness. By any economic measure, perestroika left the Soviet Union weaker than it found it.
Marker's note. A band-6 response tests the proposition rather than accepting it - granting the foreign-policy success and domestic failure but complicating the neat split by showing the shared cause - anchors each claim in dated, quantified evidence, and sets historians in tension (Brown's agency vs Zubok's structure). Simply describing the policies without evaluating "succeeded/failed" caps the response in the middle bands.
