Since the beginning of UN peace operations, there has been discussion as to exactly how they should be carried out. Thus far, a just theory of UN peacekeeping operations has not yet been formed, in the way a Theory of Just War for waging war or a theory of police ethics for law enforcement in a peace context had been formed. The article discusses what a justified risk distribution between UN peacekeepers and local civilians should be. One of the points (...) of criticism of UN peacekeeping missions is the lack of protection of the local population in the course of an escalating situation. Familiar examples are the traumas of Rwanda (1994) and Srebrenica (1995). Discussing differences between UN peacekeeping missions, warfare, and law enforcement, it appears that peacekeepers have more in common with law enforcers than with combatants during wartime. Through the method of analogy and by applying some typically military ethics principles, the moral status of the UN peacekeepers is analyzed. Finally, a risk distribution analysis between UN peacekeepers and the local population is carried out, by offering a concise overview by philosophers of arguments for and against taking fewer risks by peacekeepers. The analysis reveals important deontological and consequentialist arguments. Taking also into consideration that transferring more risk to the peacekeeping troops alone does not mandatory lead to less exposure to risk of the vulnerable and innocent local civilians, it can be concluded that a more practical, virtuous, responsible risk calculation will be necessary at that point to find the best risk distribution.
