The events relating to Iraq have been critical in defining the post-Cold
War inter- national system of peace and secnrity. Dealing with Iraq
covered the whole legal, political and emotional spectrum. The initial
triumphalism was replaced by cyni- cism and apathy, ending in division
and enmity. Above all, it raised questions about the political and legal
foundations of the international secnrity system, its players and their
interests. The object of the present paper is to examine the cnr- rent
meaning and nature of the collective secnrity system premised on the
United Nations. An understanding of the flaws and problems associated
with the prac- tice of this system will enable us to rethink its basis
and propose a conceptual framework for its reconstitution on the basis
of legitimacy, using the war on Iraq as a case study to illustrate onr
arguments. The discussion will begin with a short presentation of the
political and legal situation leading to the war against Iraq in March
2003. This will be followed by a critical analysis of the UN collective
se- cnrity architecture as it evolved after the end of the Cold War. Onr
aim at this stage is to identify the characteristics of the system,
consider the scope of subse- quent developments in conceptual or
practical terms and discuss their signifi- cance for the international
secnrity system.
