Review Questions

• How did the dropping of Fat Man influence Japan's decision to surrender in World War II?
  • The dropping of Fat Man on Nagasaki, following the earlier bombing of Hiroshima with Little Boy, created a catastrophic impact that overwhelmed Japan's capacity to continue fighting. The sheer destructive power demonstrated by these atomic bombs highlighted the futility of further resistance against Allied forces. The combination of immense loss of life and devastation prompted Japan to reconsider its position, ultimately leading to their surrender on August 15, 1945.
• Discuss the implications of Fat Man's use on international relations in the years following World War II.
  • The use of Fat Man not only brought an end to World War II but also marked the beginning of a new era defined by nuclear diplomacy and arms races. Countries began to recognize the potential for nuclear warfare, leading to debates over disarmament and non-proliferation. The bombings prompted international discussions about military ethics and raised concerns about civilian casualties in conflicts, shaping global attitudes toward warfare and defense strategies in the ensuing Cold War.
• Evaluate how Fat Man and its deployment reflected broader themes of power dynamics and ethical considerations during and after World War II.
  • Fat Man's deployment illustrated the overwhelming power dynamics at play during World War II, particularly as it marked a shift towards total warfare that disregarded traditional limits concerning combat. The ethical implications surrounding its use have since fueled debates about morality in warfare and the justification for targeting civilian populations. This event set a precedent for future conflicts where nuclear weapons were considered, forcing nations to confront their responsibilities and choices in wielding such destructive capabilities, all while navigating a precarious global landscape.
