Compare after trying
Reagan and Gorbachev mattered through decisions that altered the relationship between pressure and bargaining. American military commitments could influence perceived costs, while Gorbachev’s reform priorities encouraged a different approach. The existence of talks before 1985 and SDI’s status as research qualify claims that one new relationship or a completed shield suddenly determined everything.
Geneva opened sustained summit dialogue with differences remaining; Reykjavik explored ambitious reductions without completing its proposed package. The later INF agreement provided a more concrete category-specific result with separate entry and implementation stages. These distinctions show how leadership could move a process forward without making each meeting complete disarmament. Overall, their contribution was substantial but mediated by institutions, advisers, allied concerns and Soviet domestic priorities. Reagan’s departure in January 1989 also leaves Bush’s later choices to explain. A persuasive judgement identifies mechanisms and dates, then weighs leadership alongside pressures and local movements rather than assigning every outcome to either force or personal rapport alone.
Why this response fits
- Connects dated evidence to a mechanism of change or continuity.
- Distinguishes an actor’s claim, an observed action and the limits of the conclusion.
Place dialogue within the earlier confrontation
Reagan’s presidency combined military commitments, strong anti-communist language and an increasing willingness to negotiate with Soviet leaders. Gorbachev’s accession in March 1985 created a new negotiating relationship, but strategic talks had already begun in 1982. The later personal relationship therefore changed the prospects of an existing process rather than inventing every arms discussion from nothing.
A pressure explanation argues that American strength made the costs of continued competition clearer. That is a claim about incentives and perceptions to test, not a licence to assume an exact Soviet budget burden or a single unavoidable response. The Strategic Defense Initiative announced in 1983 was a research proposal, not an operational shield that had already neutralised all retaliation. Its effect could operate through expectations and bargaining even without the claimed completed capability.
Distinguish summit stages and unresolved issues
At Geneva in November 1985, the leaders began direct summit dialogue while important differences remained. Reagan’s subsequent public radio address is useful evidence of how he presented the meeting and its goals. It is not proof that major arsenals had been dismantled or that either government accepted the other’s entire programme. A meeting can matter by changing contact and expectations before a comprehensive agreement exists.
Reykjavik in October 1986 explored ambitious reductions but failed to produce the broad agreement discussed, with disagreement over defensive research among the obstacles. Failure to conclude that package does not mean no useful negotiating work occurred. The INF agreement signed in December 1987 later required elimination of a defined missile category; its entry in 1988 and implementation belong to subsequent stages rather than the moment of signature.
Weigh contributions and the limits of leadership
Both pressure and accommodation may contribute to an explanation, but they work through different mechanisms. Greater perceived costs could encourage bargaining, while a willingness to accept constraints and pursue agreement could make a negotiated result possible. Show which decision supports which mechanism. Praising a leader’s personality without identifying a choice is not a causal explanation.
Gorbachev’s reform priorities, advisers, allies and local movements also shaped events. Reagan left office in January 1989, before the Wall opening and later German settlement, so Bush’s choices cannot be silently assigned to him. Conversely, later events do not erase the significance of earlier dialogue and agreements. A convincing answer compares leadership across time and alongside structural pressures and local agency. Broader records on both sides remain required before assigning exclusive credit for the end of the Cold War.

Pause and explain
Which explanation best evaluates leadership?
Worked example
Did the Geneva meeting itself establish completed nuclear disarmament?
Show the worked solution
- Identify dialogue and public presentation.
- Separate discussion from an agreed instrument.
- Distinguish signature, entry and implementation.
Answer No. Geneva advanced contact while differences remained; later instruments and verified implementation are different evidence.

Write your answer and reasoning first. Use a hint only if you are stuck. The model solution is for self-checking; your written work is not automatically marked.
Guided: Explain how pressure and dialogue can appear in the same causal argument.
Give me a hint
Identify their different effects rather than choosing a slogan.
Compare my reasoning
- Describe an incentive created by perceived costs.
- Describe a decision enabling negotiation.
- Test each against dated evidence.
Pressure could raise the perceived costs of continued competition, while dialogue and willingness to accept constraints could make a negotiated response possible. These mechanisms can interact, but neither is established by a slogan about strength or friendship. The answer should identify dated decisions, compare them with the other side’s priorities and distinguish proposals from actual agreements. This permits a judgement about contribution without assigning automatic exclusive credit.
Look for these in your work
- Explains distinct mechanisms
- Connects them to testable decisions
Independent: Assess why Reykjavik can be significant despite the absence of its broad proposed agreement.
Give me a hint
Separate an unsuccessful outcome from work within a process.
Compare my reasoning
- Identify the ambitious discussion.
- Identify unresolved disagreement over defensive research.
- Relate the work to later bargaining without calling it a signed treaty.
Reykjavik explored substantial reductions and clarified areas of agreement and disagreement, including the dispute over defensive research. It did not produce the broad package discussed, so the summit cannot be described as that completed treaty. Yet clarification and bargaining could still affect later negotiations. Its significance should be weighed within the process leading to subsequent instruments, while distinguishing a useful stage from an achieved legal agreement.
Look for these in your work
- Preserves the summit’s limits
- Explains significance within a sequence
Application: Correct an account giving Reagan responsibility for every decision in 1989-1991.
Give me a hint
Preserve continuity while identifying the change of administration.
Compare my reasoning
- Place Reagan’s departure in January 1989.
- Identify Bush’s later role.
- Retain earlier groundwork and non-American actors.
Reagan’s dialogue and agreements helped shape the relationship inherited in 1989, but he left office in January. Bush’s decisions during the Eastern European changes, German settlement and Soviet breakup need separate treatment. Gorbachev, advisers, allies and local movements also retained agency. A corrected account can recognise earlier groundwork without giving one former president direct responsibility for every later choice or treating the sequence as automatic.
Look for these in your work
- Keeps the presidential chronology clear
- Balances continuity with distinct later choices
Common mistakes
- Making SDI an operational shield
- Calling Reykjavik a completed comprehensive treaty
- Attributing Bush-era decisions automatically to Reagan
