Since Bosnia and Herzegovina is a state where various interests are differentiated in a special way provoking constant turmoil and debates in the international community due to a series of contradictions , and the state that „owes“ its newly acquired independence to numerous compromises achieved through the engagement and often direct pressure from the international community, the paper is focused on the presentation of the role of NATO from the period when it started to be involved in resolving the crisis until the Dayton Agreement was reached. The main goal of the paper is to illustrate the role of NATO being a powerful military organisation controlled by the limitations of unstable politics that required the inclusion of armed forces in the situations with no political solution in response to the crisis during the war in Bosnia and Herzegovina from 1992 until 1995. Guided by its specific goals, the task of the paper is to present the situation that has caused serious and alarming internal divisions in this organisation, significantly damaged its reputation, initiated the discussions about its purpose, and finally, after overcoming all difficulties, resulted in its engagement that has helped it to preserve and in some segments also to strengthen its global position and role. The paper highlights the problem of dual competence shared by the United Nations and NATO as specially limiting mechanism related to the approval of each concrete military operation that was consequently slow and limited, and very often the military forces of the Alliance failed to be engaged at all with tragic consequences for the victims of aggression. Consequently, the most powerful military alliance has become a victim of political hesitation and outwitting and one of the frequent targets of international public criticism and accusations. This paper will therefore point to some less known facts that have affected the crucial decision of the Alliance that nearly stopped its engagement in the failed mission Deliberate Force intended to „retrieve“ the UN forces from the territory of Bosnia and Herzegovina, which made the world community and the USA admit to be powerless in ending the war.
