Abstract
Intervention has to be considered as a moral problem which has become all the more accurate that intra-state conflicts have dramatically increased. In the case of an inter-states conflict, military intervention can be both lawful and moral. But, in the case of an intra-state conflict, if no legality is possible, the issue of morality becomes the only criterion. Hence, is it possible to justify morally the principle of military intervention? Should intervention be considered justified as a principle or according to each situation?
