      Lesson details

      Learning outcome

      I can explain why there was not a sustained improvement in US-Soviet relations after the Helsinki Accords.

      Key learning points

      1. The Helsinki Accords were an attempt to reach agreement on security, international cooperation and human rights.
      2. The Helsinki Accords are sometimes considered to be the high-point of Détente.
      3. Disagreements about human rights were one source of tension between the USA and the USSR after Helsinki.
      4. By the end of the 1970s, hopes for improved relations between the USA and the USSR had faded.
      5. The USA and USSR signed SALT II but after the Soviet invasion of Afghanistan it was not ratified in the USA.

      Keywords

      • Détente - the relaxation of tensions between states which were previously hostile towards one another

      • Accords - formal agreements between two or more parties

      • Human rights - the basic freedoms and protections that all people are entitled to, simply because they are human

      • Ratified - when a decision, treaty, or agreement is formally approved and confirmed making it official

      Common misconception

      Détente ended suddenly following the Soviet invasion of Afghanistan in December 1979.

      The Soviet invasion of Afghanistan is normally considered to mark the end of Détente but US-Soviet tensions had been increasing since 1975 due to conflict over human rights issues and increased Soviet support for communist groups around the world.

      Teacher tip

      Students should practise sequencing the key events of the 1970s and identifying the connections between them in order to develop their skills at writing analytical narratives.
