The United Nations and International Security in the New Millennium
The end of the Cold War opened a window of opportunity for the United Nations to play a greater role in international security than it was allowed to play in the midst of the ideological conflict between the United States and the former Soviet Union. However, the expected "peace dividend" never materialized in the post-Cold War period. Instead, a number of civil conflicts erupted and new threats to security, particularly to human security, emerged. This chapter critically examines the evolution of the UN's role in addressing international security problems since 1945, including global terrorism. It also outlines recent attempts by the world body, through extension of its reach beyond the territorial constraints of sovereignty, to build sustained peace through preventive measures and protect human security globally.
