Issues of moral well-being among soldiers, such as morale and moral injury, are predominantly approached as individual and psychological concerns. Current interventions tend to emphasize bolstering soldiers’ individual resilience by instilling a sense of justification and purpose. Yet, paradoxically, such an approach can foster behavior in soldiers that later results in deep regrets and a sense of betrayal toward military and political leaders. This article starts from the contention that issues of morale and moral injury should also be addressed at (...) the political decision-making level. It explores the significance of macro-level political-philosophical traditions such as Just War Theory for morale and moral injury at the micro-level, and, consequently, its implications for our understanding of resilience. Just War Theory, understood as a balance between Weber’s ethics of conviction and ethics of responsibility, is shown to hold the potential for informing morally responsible political decision-making and protecting soldiers’ well-being. However, this depends on using Just War criteria as genuine guiding principles, viewing them as interconnected criteria rather than checkboxes, and involving all relevant stakeholders. Also, low morale should not be readily approached in negative terms. Rather, resilience should be recognized as having complex ethical and contextual dimensions. (shrink)
