Preventive UN Diplomacy and International Peace After the Cold War

With the end of the Cold War and the bipolar system of international relations and consequently the establishment of international peace, the international system has undergone profound changes and has experienced new features and variables. According to this paper, the concept of international peace has been in a very critical and deplorable state since the 1990s, and the mechanisms for achieving peace, including the United Nations' preventive diplomacy as the sole institution for the realization of international peace was both ineffective and inefficient in preventing bloody conflicts and large-scale genocides in comparison with the Cold War era. This article seeks to answer the question that how is the performance of UN preventive diplomacy assessed in the post-Cold War era? In response to this question, it is hypothesized that the performance of UN preventive diplomacy in the post-Cold War era has not been successful due to its weakness and inefficiency in resolving armed conflicts in order to achieve international peace.
