Make a guess
Ronald Reagan became US president in 1981, soon after detente had collapsed. What do you think his approach to the USSR was?
- Confrontation: a military build-up, SDI and aid to anti-communist rebels.
- Withdraw US forces from Western Europe to save money.
- Revive detente straight away with new trade deals and summits.
Show the answer
Confrontation: a military build-up, SDI and aid to anti-communist rebels.
Reagan saw the Soviet system as dangerous but weak, so he raised spending and pressure, and tension peaked in 1983.
Reagan revived confrontation with a military build-up, SDI, hard-line rhetoric and support for anti-communist rebels.
Detente collapsed after the Soviet invasion of Afghanistan in December 1979. Ronald Reagan became president in 1981 believing the USA had fallen behind and that the Soviet system was both dangerous and weak.
Reagan expanded defence spending sharply. In March 1983 he called the USSR an "evil empire" and announced the Strategic Defense Initiative (SDI), a research programme for defences against ballistic missiles. Soviet leaders feared SDI would let the USA strike first without fear of retaliation, and that matching it would be ruinously expensive.
The Reagan Doctrine meant supporting anti-communist insurgents against Soviet-backed governments. The USA armed the mujahideen in Afghanistan, including with Stinger missiles from 1986, the Contras in Nicaragua and UNITA in Angola. This raised the costs of Soviet commitments abroad.
Tension peaked in 1983. The Soviets shot down Korean Air Lines Flight 007 in September. In November, the NATO exercise Able Archer alarmed Soviet leaders, who feared it might hide a real attack.

Real examples to use
Defence build-up, 1980 to 1985
US defence spending was about 134 billion dollars in 1980. By 1985 it was roughly 40 per cent higher after inflation, which the USSR could only match by spending even more of a weaker economy.
KAL 007, 1 September 1983
A Soviet fighter shot down a Korean airliner that had strayed into Soviet airspace, killing all 269 people on board. It marked a low point in superpower relations.
Stinger missiles, 1986
From 1986 the USA gave Afghan mujahideen Stinger missiles that could shoot down Soviet helicopters, raising the cost of the war for Moscow.
Worked example: Using renewed confrontation in an argument
An assertion source says American pressure forced the USSR to change.
- Support: the build-up, SDI and the Reagan Doctrine raised Soviet costs.
- Challenge: Soviet hardliners responded to pressure with more suspicion, not concessions.
- Timing: major Soviet change came only after Gorbachev took power in 1985.
- Judgement: pressure mattered, but it needed a Soviet leader willing to change course.
Watch out for this
SDI was a working missile shield that made Soviet missiles useless.
SDI was a research programme. It never produced a working shield, but Soviet leaders feared its potential and the cost of competing.

Supporting anti-communist insurgents against Soviet-backed governments
Right. Examples include Afghanistan, Nicaragua and Angola.
