Review Questions

• How did the development of nuclear weapons influence military strategies during the Cold War?
  • The development of nuclear weapons led to a fundamental shift in military strategies during the Cold War. Nations began to focus on deterrence as a primary military doctrine, relying on the threat of devastating retaliation to prevent conflicts. This led to strategies like Mutually Assured Destruction (MAD), where both superpowers maintained large arsenals to discourage any first-strike attempt. The presence of these weapons made conventional warfare less likely but increased tensions as countries raced to build more advanced technologies.
• Discuss the impact of nuclear weapons on international relations and diplomacy during the Cold War.
  • Nuclear weapons profoundly affected international relations during the Cold War by creating a tense geopolitical environment marked by competition and mistrust. The arms race between the United States and the Soviet Union not only shaped their bilateral relations but also influenced alliances worldwide. Diplomatic efforts such as arms control treaties emerged in response to the potential for catastrophic conflict, highlighting the need for negotiations and cooperation among nations to prevent nuclear proliferation and maintain global stability.
• Evaluate how public perception of nuclear weapons changed from their introduction in World War II to the later stages of the Cold War.
  • Public perception of nuclear weapons evolved significantly from their introduction in World War II to later stages of the Cold War. Initially viewed as a means to end conflict swiftly and decisively, concerns about their destructive power grew as awareness spread regarding their long-term consequences and potential for mass destruction. By the 1960s and 1970s, anti-nuclear movements gained traction, with citizens advocating for disarmament and expressing fear over accidental launches or miscalculations. This shift prompted greater calls for transparency, regulation, and international cooperation aimed at reducing nuclear arsenals and preventing future conflicts.
