Review Questions

• How did the development of the atomic bomb impact the nature of global conflict in the 20th century?
  • The development of the atomic bomb dramatically changed the nature of global conflict by introducing a new level of destructive capability that had never before been seen in warfare. This weapon not only ended World War II but also instilled a sense of fear regarding future conflicts, as countries realized that any major war could potentially escalate into a nuclear confrontation. The bomb's existence shifted military strategies towards deterrence rather than direct confrontation, as nations sought to avoid catastrophic outcomes.
• Discuss the ethical considerations surrounding the use of atomic bombs during World War II.
  • The use of atomic bombs in Hiroshima and Nagasaki raised significant ethical questions about the morality of using such devastating weapons against civilian populations. Critics argue that the bombings were unnecessary for achieving Japan's surrender, while proponents contend they saved lives by preventing a prolonged ground invasion. These debates highlight the complex interplay between military strategy and humanitarian concerns, as well as the lasting implications for international relations and nuclear policy.
• Evaluate the long-term effects of atomic bomb development on international relations and military strategy throughout the Cold War period.
  • The development and use of atomic bombs had profound long-term effects on international relations and military strategy during the Cold War. It led to an arms race between superpowers, as countries invested heavily in nuclear arsenals to deter potential attacks. The doctrine of Mutually Assured Destruction (MAD) emerged, where both sides recognized that any nuclear conflict would result in total annihilation. This precarious balance created a tense but stable situation known as 'nuclear deterrence,' fundamentally shaping diplomatic strategies and alliances during this period.
