ABSTRACT
This chapter addresses the United Nation's (UN's) experiences in peacekeeping and peace enforcement since the late 1980s. It discusses the problems which have arisen regarding the legitimacy of intervention, the limitations of the UN's peacekeeping capabilities, and the dilemmas of peace enforcement. The chapter examines some of the ways in which these problems have been addressed: limited reforms of the UN's capabilities have been carried out; stricter guidelines on the establishment of peacekeeping operations have been drawn up; and regional organisations have been increasingly relied on to help maintain international peace and security. In the 1990s, reforms have been carried out in the UN's peacekeeping and peacekeeping set-up, reflecting the transition to the "fourth phase" in the development of the role of global international organisation in the area of international peace and security. The Security Council would have much improved access to information concerning security questions through an office under the Secretary-General, and an enhanced capacity for analysing that information.
