The joint international action against Iraq and the search for a new security doctrine following the end of the Cold War, led, in the early '90s, to a revival of the notion of collective security embodied in several international agreements. This notion is based on the assumption of responding collectively to international aggression. However, the international guagmires of recent years and especially the case of former Yugoslavia where international organizations have played the role of alibi to agression, has once more, dealt a major blow to the illusion of the implementation of the principles of collective security. In a way similar to the 1930s and the bipolar balance of power of the Cold War, collective security seems ephemeral today. We can therefore safelypredict that in the foreseeable future, international relations will continue to be shaped by the balance of specific state interests and not by universally applied principles of collective security.
