Providing a comprehensive overview of the war and the issues connected with it, the author examines the origins of the conflict historically and traces how both sides were dragged inexorably into war in the early 1990s. The book discusses the two wars (1994-96 and 1999 to date), the intervening truce and shows how a downward spiral of violence has led to a mutually-damaging impasse from which neither side has been able to remove itself. It applies theories of conflict, especially theories of terrorism and counter-terrorism and concludes by proposing some alternative resolutions that might lead to a just and lasting peace in the region.
