Review Questions

• How does Just War Theory differentiate between just reasons for entering war and the conduct during warfare?
  • Just War Theory separates its principles into two main categories: 'jus ad bellum' and 'jus in bello.' 'Jus ad bellum' outlines just causes for entering a conflict, requiring factors like legitimate authority and just cause. In contrast, 'jus in bello' focuses on the moral conduct during war, emphasizing rules like proportionality and the distinction between combatants and civilians. This differentiation helps guide ethical decision-making before and during military actions.
• Discuss how historical cases have shaped the evolution of Just War Theory in relation to international responses to conflict.
  • Historical cases like World War II and the Vietnam War have significantly impacted Just War Theory by highlighting moral dilemmas faced during warfare. For instance, the response to Nazi aggression raised questions about preemptive strikes versus waiting for an attack. These events prompted revisions to ethical guidelines, contributing to modern international responses that seek to enforce humanitarian principles through treaties and organizations. Such cases illustrate how theory adapts based on practical realities of conflict.
• Evaluate the relevance of Just War Theory in contemporary discussions about humanitarian interventions and military operations.
  • Just War Theory remains highly relevant in contemporary discussions about humanitarian interventions, especially as conflicts like those in Syria or Libya arise. Debates center around whether interventions are justified under 'jus ad bellum,' particularly regarding legitimacy and humanitarian need. Additionally, 'jus in bello' considerations influence how military operations are conducted to minimize civilian casualties. Analyzing these scenarios through the lens of Just War Theory encourages critical evaluation of ethical standards in modern warfare, challenging policymakers to align actions with moral imperatives.
