• Les migrations internationales sont devenues l'un des enjeux majeurs des rapports entre les États. Dans ce cadre, les mouvements de réfugiés et de déplacés liés aux conflits politiques, identitaires ou territoriaux témoignent de la fragilité de constructions nationales encore si souvent contestées. Les principales modalités d'accueil des réfugiés montrent bien les obstacles à l'intégration comme les limites d'une assistance humanitaire dont l'action reste plus curative que préventive. Mais la paix revenue, le retour et la réintégration des réfugiés dans leur pays d'origine se heurtent encore à des difficultés politiques, juridiques et économiques qui sont autant de freins à la reconstruction nationale et qui, par là même, dessinent les migrations internationales du futur. Tels sont quelques-uns des grands thèmes évoqués dans les différentes contributions de cet ouvrage, dont certaines, comme celles sur les camps palestiniens du Liban, sur la revendication territoriale des Sahraouis ou encore sur le difficile retour des réfugiés cambodgiens, sont d'une actualité toujours brûlante. International migration has become one of the major issues in relations between states. Within this framework, movements of refugees and displaced persons resulting from political, identify or territorial conflicts show the fragility of national constructions that are still so frequently contested. The main procedures for hosting refugees clearly show the obstacles to integration and the limits of humanitarian aid, whose action is more curative than preventive. However, when peace is restored, the return and re-integration of refugees in their home countries still corne up against political, legal and économie difficulties that ail hinder national reconstruction and also indicate the pattern of future international migration. These are some of the major themes mentioned in the various contributions to this study, some of which are still extremely topical, such as those concerning the Palestinian camps in the Lebanon and the territorial daim of the Sahraouis.

  • Since the mid-19th century military powers and various writers have tried to define the notion of belligerent occupation and, in particular, the beginning thereof. There are many situations in which a state of occupation is controversial or even denied. When is control so effective that an invasion turns into a state of belligerent occupation? What is the minimum area of a territory that can be occupied; a town, a hamlet, a house or what about a hill taken by the armed forces? This paper examines what seems to be an important gap of the Fourth Geneva Convention: contrary to the Hague Regulations of 1907 it does not provide a definition of belligerent occupation. It is argued that the Fourth Geneva Convention follows its own rules of applicability and that therefore the provisions relative to occupied territories apply in accordance with the "functional beginning" of belligerent occupation approach from the moment that a protected person finds him or herself in the hands of the enemy.
