Can Just War Theory apply to modern conflicts?

Yes, Just War Theory can apply to modern conflicts, although its application may be complex and nuanced.

Just War Theory, a doctrine of military ethics, has been a cornerstone of Western philosophy and international relations for centuries. It provides a moral framework for evaluating the justification and conduct of war, based on principles such as just cause, proportionality, and last resort. Despite its historical roots, this theory remains relevant in the context of modern warfare, offering a lens through which to scrutinise contemporary conflicts.

However, the application of Just War Theory to modern conflicts is not without challenges. The nature of warfare has evolved significantly, with the rise of non-state actors, cyber warfare, and drone strikes, blurring the traditional lines of battlefields and combatants. This raises questions about how principles like discrimination (distinguishing between combatants and non-combatants) and proportionality can be applied in these contexts. For instance, in a drone strike, who is considered a legitimate target? How can collateral damage be minimised or justified?

Moreover, the principle of 'just cause' can be contentious in modern conflicts. While traditional just causes such as self-defence or protection of innocents are straightforward, what about pre-emptive strikes against perceived threats, or humanitarian interventions in other countries' internal affairs? These scenarios highlight the need for ongoing debate and reinterpretation of Just War Theory in light of contemporary realities.

Despite these complexities, Just War Theory remains a valuable tool for ethical analysis of modern conflicts. It encourages critical thinking about the moral implications of warfare, pushing us to consider not just the strategic or political dimensions, but also the human costs. It prompts us to ask difficult questions about the justification and conduct of war, and to hold states and other actors accountable for their actions. Thus, while its application may be complex and nuanced, Just War Theory can indeed apply to modern conflicts.
