In this chapter, we consider the plausibility and consequences of the use of the term “honest errors” to describe the accidental killings of civilians resulting from the US military’s drone campaigns in Iraq, Syria, Afghanistan, and elsewhere. We argue that the narrative of “honest errors” unjustifiably excuses those involved in these killings from moral culpability, and reinforces long-standing, pernicious assumptions about the moral superiority of the US military and the inevitability of civilian deaths in combat. Furthermore, we maintain that, given (...) the knowledge-distorting practices within the US military’s organizational structure, few if any civilian deaths from drone strikes meet the criteria of a genuinely morally excusing “honest mistake”. Instead, these accidental killings often reflect objectionable attitudes of relative disregard for the safety of civilians. These attitudes are, we argue, sufficient to warrant the attribution of blame and moral responsibility, both with respect to certain individual actions and with respect to the US military as an institution. In light of this, we propose incorporating a Principle of the Moral Equality of Non-combatants into military assessments of what counts as “acceptable risk” to civilians. This would go some way, we argue, to redressing the ongoing injustice inflicted on the victims of civilian killings by the failure of the US military and US political leadership to take moral responsibility for unjustified civilian deaths.
