What began as a tentative attempt has come to be accepted as a regular feature of the UN's activities. Often, it is the most visible aspect of the UN, determining its image in public perceptions. The United Nations is uniquely placed to play the peace-keeping role. It is the only truly universal organisation that we have. Its political authority cannot be matched by efforts of individual States or regional arrangements.
History is witness to national wars, or wars fought by military alliances.
Their objectives have often been territorial or ideological gains. What is unique about UN peacekeeping is that it reflects universal objectives, rather than partisan interests. The most successful model of peacekeeping which evolved is based on consent of the host State. The consensual approach to peacekeeping is as relevant today, as it was in the past. This was reinforced by UN's experience in Somalia.
