Reasons for Détente (AQA GCSE History) : Revision Note
Was the 1970s the right time to pursue détente? - Summary
Détente is the French word for 'relaxation'. In a Cold War context, détente means to pursue a period of peace between two hostile countries.
The 1970s provided the perfect opportunity to improve US-Soviet relations. The stockpiling of nuclear weapons was one of the causes of the Cuban Missile Crisis. Through narrowly avoiding nuclear warfare, the USA and the Soviet Union had more motivation to form better relations. Both countries agreed on the concept of Mutually Assured Destruction (MAD). The term means that the USA and the Soviet Union recognised that they held enough nuclear weapons to destroy each other.
By the 1970s, the USA and the Soviet Union faced challenges within their own countries. The nuclear arms race distracted the leaders of the USA and the Soviet Union from serious domestic concerns. Pursuing détente allowed both countries to resolve their internal issue. Cold War tensions resumed in the 1980s.
China-Soviet Split
Sometimes called the 'Sino-Soviet Split'
Refers to the growing tension between China and the Soviet Union during the 1960s
The split occurred because:
Mao believed the Soviet Union under Khrushchev had become too soft and was betraying true communist values
Mao also disagreed with peaceful co-existence with the West, which Khrushchev promoted
Relations became so bad that, in 1969, there were armed clashes along the Ussuri River on the border between China and the USSR
This broke down the two countries' diplomatic relationship
Why did the China-Soviet Split help détente?
The China-Soviet Split caused a division in the communist world
The Soviet Union no longer had full control or support from other communist countries
As a result, the Soviet Union was more open to improving relations with the USA through détente
They wanted to avoid isolation and balance the growing threat from China
The USA also saw an opportunity
They improved relations with China
In 1972, President Richard Nixon became the first US president to visit China

Consequences of the Vietnam War
The Vietnam War was long, costly, and unpopular in the USA
Over 58,000 American soldiers died
Just in 1968, the USA spent $84 billion on its military
There were mass protests in the USA to force the government to withdraw US troops from the conflict
The war damaged America’s reputation around the world and caused deep divisions at home
Why did the end of the Vietnam War help détente?
After the war, the USA was more cautious about getting involved in further conflicts
This encouraged peaceful diplomacy over direct confrontation
The USA hoped détente would reduce the chance of another war like Vietnam
Issues with nuclear weapons
Both the USA and the USSR had stockpiled nuclear weapons
By 1967, the US possessed 31,255 nuclear warheads
In comparison, the Soviet Union had an estimated 8,400
These weapons were so powerful they could destroy both countries many times over
Why did the risk of nuclear warfare help détente?
The fear of a nuclear war during the Cuban Missile Crisis made both sides realise they needed to control the arms race
Reducing the risk of nuclear war became a top priority during the 1970s
This led to agreements like SALT I
Examiner Tips and Tricks
Be careful not to confuse why détente started with what détente achieved. If the question is about the reasons for détente, don’t focus too much on what happened after it began.
For example, SALT I is a result of détente, not a reason for it.
Economic issues in the 1970s
The Soviet economy
The Soviet economy was struggling, especially with the cost of keeping up in the arms race
The Soviet Union was spending 20% of its GDP on its defence budget
As the communist economy was not growing, the Soviet Union could not sustain this military spending
The country produced very poor quality consumer goods in comparison to the USA
This limited the Soviet Union to selling products within their own country
The standard of living in the Soviet Union was lower than in the USA
Houses were unsafe
People had harsh and dangerous working conditions
The government abused their citizens' human rights
The US economy
After the Vietnam War, the US government was in a large amount of debt
The US also faced rising amounts of inflation
This made the cost of living in the USA higher than it had been before the war
Why did economic issues help détente?
The Soviet Union
Détente gave the Soviet Union a chance to:
focus on fixing their economy
get access to Western trade and technology
The USA
Détente gave the USA a chance to:
reduce their military spending
focus on their domestic issues after the Vietnam War
Examiner Tips and Tricks
An exam question could ask you how far you agree that the the Soviet invasion of Czechoslovakia was the main cause of tension in the 1960s.
Conclusions are usually where most of your judgement marks will be awarded. Students often rush their conclusions so they are not as developed as they could be. All great conclusions have these three elements:
Judgement – Start with your opinion. Try to include the words from the question. Consider second-order concepts like short- and long-term consequences, change and continuity and significance
Counter – Give an example from the other side of the argument to show your awareness of this
Support – Explain why, after considering all the evidence, you have reached your judgement. Use your best piece of evidence to show your opinion
For further guidance on this question, you can read this revision note on how to answer the 16-mark “How far do you agree” question.
