The end of the cold war has not brought greater security to the world. Although the likelihood of global nuclear war has been reduced, other threats to international peace-are becoming increasingly evident. As the Gulf War of 1991 demonstrated, regional conflicts can expand, adopting the methods and means of the earlier superpower confrontation. Written by international authorities in a wide range of disciplines, the essays in this book examine what is known, what must be determined, and what might be done with respect to these profound and urgent issues.
