Syllabus 8838, Theme I, Learning Outcomes. evaluate the causes for the end of the Cold War
Make a guess
Reagan called the USSR an "evil empire" in 1983. What do you think he and Gorbachev signed in December 1987?
- A treaty scrapping a whole class of nuclear missiles.
- A treaty to scrap the nuclear weapons of both sides by 2000.
- No treaty, because Reagan refused to negotiate with Soviet leaders.
Show the answer
A treaty scrapping a whole class of nuclear missiles.
The INF Treaty eliminated intermediate-range missiles and allowed on-site inspections, which built trust.
Reagan combined pressure with negotiation, and with Gorbachev reached the INF Treaty in 1987, the first to eliminate a class of nuclear weapons.
Reagan was not only a hawk. He believed nuclear weapons should be reduced and even abolished, and he was willing to negotiate from strength.
After Gorbachev came to power in 1985, the two leaders met at Geneva in November 1985. At Reykjavik in October 1986 they came close to agreeing to abolish all nuclear weapons, but talks broke down because Reagan refused to limit SDI.
In December 1987 they signed the Intermediate-Range Nuclear Forces (INF) Treaty. It eliminated an entire class of missiles and allowed on-site inspections, which built trust. The START I treaty to cut long-range weapons was signed in July 1991.
Historians debate who deserves the credit. Some stress Reagan's strength, which made the USSR negotiate. Others stress that Gorbachev made most of the concessions, accepting US proposals such as the "zero option" on intermediate missiles.
- Geneva summit
- November 1985.
- Reykjavik
- October 1986: near agreement; SDI the obstacle.
- INF Treaty
- December 1987: eliminates intermediate-range missiles.
- START I
- July 1991.
Real examples to use
Reykjavik, 11 to 12 October 1986
Reagan and Gorbachev discussed scrapping all nuclear weapons, but no deal was reached because Reagan would not limit SDI.
INF Treaty, 8 December 1987
By June 1991 the USA had destroyed 846 missiles and the USSR 1,846, a total of 2,692. It was the first treaty to cut nuclear weapons rather than cap them.
START I, 31 July 1991
Bush and Gorbachev agreed to limit each side to 6,000 long-range warheads on 1,600 missiles and bombers.
Worked example: Who drove arms control?
A source shows a Soviet official saying the USSR had compromised on key issues.
- Support for Soviet initiative: Gorbachev accepted the zero option and inspections.
- Support for Reagan: he set the terms and kept SDI as leverage.
- Cross-reference: Reykjavik failed over SDI, yet the INF Treaty followed.
- Judgement: agreement needed both a willing Reagan and a reforming Gorbachev.
Watch out for this
The INF Treaty ended the nuclear arms race.
It eliminated intermediate-range missiles only. Strategic weapons remained, and START I came later, in 1991.
Check your understanding
Why did the Reykjavik summit fail to reach a full agreement?
- Gorbachev refused to discuss nuclear weapons.
- Reagan refused to limit SDI.
- The summit was cancelled.
Show the answer
Reagan refused to limit SDI.
Right. SDI was the sticking point.
