1.0 INTRODUCTION

1.1   BACKGROUND

The challenges to establish and maintain law, order, peace and security have preoccupied humanity since political communities emerged on the surface of earth. (Stedman, 1991). These have been occasioned by the manifestation of conflict as part of the feature of human relations. (Stedman, 1991).

The need for peace and security has been addressed with the creation of the state as a political community. The state has carried out this task through government and its institutions to keep in check the prosperity of man to express whatever disagreement there is through violence. This is done for the most part, through the restraining power of the law and sometimes through the use of force (Stedman, 1991).

At the level of relations among state where the same need for peace and security which has challenged them internally is found, the approach has been different State have had to employ common mechanism to deal with the problem of conflict. A most enduring framework is that of collective security which is expressed through Peace Supports Operation (PSO), (United Nations, 50 years of United Nations: Notes for Speakers (New York United Nations, 1995).

Dramatic events of the 1990s and the subsequent collapse of the Warsaw Pact heralded profound changes in the international security arena. With the collapse of Soviet Union, many nations’ armed forces have had to shift their institutional emphasis from fighting to maintaining stability and to prevent fighting. With it also comes the need for leaders and soldiers to participate extensively in operation designed to deter wars, resolve conflicts, promote peace and support civil authorities in respond to crisis (Azazi, 2009).    Nigeria as a member of United Nations (UN) has been one of the leading countries that participated in PSOs in the world at large and Africa continent in particular. This is in attainment of one of her foreign policy objectives (United Nations, 1995).
