Abstract:
A comparative study of the Kosovo Crisis in 1998 and the Iraq Crisis in 2003, has shown that in both cases the United Nations was not able to stop or solve the problems. Its roles involved merely with the management of humanitarian assistance after the end of the crisis. The situation turned to be that the United States of America, by means of its super military power, attempted to solve the crisis. However, the U.S.'s implementation of its policy was unilateral, claiming its legitimacy in its intervention into the crisis. The U.S.'s military operations were by no means approved by the U.N. They were considered as violating the U.N.'s charters and destroying the international peacekeeping and security system. For this reason, the U.N. needs to change and improve its roles so as to establish itself as the center of international peace and security. It has to adjust its roles in order to be able to solve international conflicts more quickly and in a more efficient manner. If the U.N. still uses the traditional way in international peacekeeping and security in the new world, it may have to face obstacles and confront with unexpected problems. When the U.N. is left in the condition where it can not deal with problems and gives the chance to other countries to intervene, this will result in more serious damages to international communities.
