Drawing on over 150 interviews with former IRA, INLA, UVF and UFF prisoners, this is a major analysis of why Northern Ireland has seen a transition from war to peace. Most accounts of the peace process are 'top-down', relying upon the views of political elites. This book is 'bottom-up', analysing the voices of those who actually 'fought the war'. What made them fight, why did they stop and what are the lessons for other conflict zones?
