Do a threatened state’s obligations of assistance extend to the enemy’s needy people and the needy people in non-hostile countries equally? This paper examines five arguments defending the political boundary between hostile and non-hostile countries. The aid workers, defence capacity, and pre-emptive self-defence arguments highlight the unreasonable burdens for a threatened state to protect its own citizens, as a result of its assistance to the enemy’s needy people, while the limited and comprehensive negative duties arguments underscore a threatened state’s involvement in harmful activities. Unfortunately, these five arguments cannot accomplish the task. Certain arguments (i.e. the aid workers argument and the negative duties approach in general) encounter the insufficiency problem by not completely denying the potential for assisting the enemy’s needy people, while other arguments (i.e. the defence capacity, the limited and comprehensive negative duties, the pre-emptive self-defence arguments) face the over-extension problem by prohibiting assistance to needy people in nonhostile countries. Therefore, when a threatened state provides assistance to needy foreigners, the distinction between hostile and non-hostile countries should not constitute a decisive reason to affect the distribution of its assistance, because it cannot clearly maintain this distinction.

This paper first argues that a state can justifiably fight a hopeless war of self-defense when its enemy determines to massacre its people after it surrenders or is defeated. The main reason is that, in this situation, even if the victim state surrenders, it still has to suffer from harms that are similar to or worse than the harms involved in fighting a hopeless war. This paper then discusses some complicated issues raised by applying this argument to various situations in which the victims of war and the victims of massacre are not identical. I argue that, when the victims of massacre are randomly chosen, the victim state can justifiably fight such a war. When the victims of massacre belong to a specific group of people, the victim state should not fight such a war, even though the victims of massacre can defend themselves. This paper finally comments on an alternative approach to addressing the same issue.
