Review Questions

• How does Just War Theory differentiate between just cause and right intention in the context of jus ad bellum?
  • Just War Theory emphasizes that just cause refers to a legitimate reason for going to war, such as self-defense or protecting innocent lives. Right intention is equally important as it stresses that even if a cause is just, the motivations behind waging war must be noble—aiming for peace rather than revenge or territorial gain. This distinction is vital to ensuring that warfare aligns with moral principles.
• Discuss the role of papal authority in shaping Just War Theory during the medieval period.
  • During the medieval period, papal authority significantly influenced Just War Theory by providing moral legitimacy to certain military actions. The Church often sanctioned wars that were deemed just, framing them as holy endeavors to defend Christianity or protect the innocent. This endorsement from the papacy helped establish a framework where moral considerations guided warfare, reflecting a deep connection between religious belief and political action.
• Evaluate how modern interpretations of Just War Theory address contemporary ethical dilemmas in military intervention.
  • Modern interpretations of Just War Theory confront contemporary ethical dilemmas by adapting its principles to address issues such as humanitarian intervention and preemptive strikes. Scholars debate how traditional criteria like just cause and proportionality apply to conflicts involving non-state actors or interventions aimed at preventing atrocities. This ongoing evaluation reflects the dynamic nature of ethics in warfare, demonstrating how Just War Theory continues to inform discussions about moral responsibilities in global politics today.
