      Lesson details

      Learning outcome

      I can explain the significance of the SALT I treaty.

      Key learning points

      1. The USA and USSR followed a policy of Détente during the 1970s.
      2. The USA and USSR wanted to divert money spent on the arms race to address domestic social and economic problems.
      3. The USA pursued a policy of Détente because they thought it would help them to end their involvement in the Vietnam War.
      4. The SALT I agreement included important limitations on arms and agreements between the USA and the USSR to cooperate.
      5. SALT I had significant limitations, for example, not all nuclear weapons were covered by the agreement.

      Keywords

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

      • Arms race - when countries compete with each other to build up their military strength

      • Domestic - issues that exist within a country, rather than those related to its relationship with other countries

      • Interim - something that is temporary

      • Rapprochement - the development of friendlier relations between countries that have been enemies

      Common misconception

      The period of Détente in the 1970s did not mark the beginning of the end of the Cold War.

      Although there was a reduction in tensions between the USA and the USSR during the early 1970s, tensions had increased again by the end of the decade.

      Teacher tip

      Get students to reflect on East-West relations over the course of the period from 1945-72 by constructing a time-axis graph. The line element of this should be plotted according to how cooperative/tense US-Soviet relations were at given times. Justifications should be included.
