Review Questions

  • How did the Detente Period change the nature of U.S.-Soviet relations during the Cold War?
    • The Detente Period fundamentally altered U.S.-Soviet relations by moving from an era defined by direct confrontations to one focused on diplomatic dialogue and negotiation. This period saw both nations pursuing arms control agreements like the SALT treaties, which aimed to curtail nuclear arsenals and prevent escalation into military conflict. Additionally, there were cultural exchanges and cooperative efforts that reflected a mutual understanding of the need for stability during a tense era.
  • Evaluate the impact of the Helsinki Accords as part of the Detente Period and their implications for East-West relations.
    • The Helsinki Accords were crucial in framing East-West relations during the Detente Period. By emphasizing respect for human rights and territorial integrity, the accords provided a platform for dialogue that sought to foster better communication between Eastern and Western blocs. However, while they were initially seen as a diplomatic success, their implementation varied significantly across countries, leading to differing interpretations and occasional tensions as dissident movements gained momentum in Eastern Europe.
  • Analyze the reasons behind the decline of detente in the late 1970s and how it influenced subsequent Cold War dynamics.
    • The decline of detente in the late 1970s can be attributed to several factors, including increasing ideological differences, domestic pressures within both superpowers, and external conflicts such as the Soviet invasion of Afghanistan. This invasion marked a pivotal moment that reversed progress made during detente, as it reignited fears in the West about Soviet expansionism. The resulting shift led to heightened military spending and renewed tensions that intensified Cold War dynamics throughout the 1980s, setting back many of the diplomatic gains achieved earlier.
