Among the more frequent and most devastating of conflicts, civil wars—from Yugoslavia to Congo—frequently reignite and even spill over into the international sphere. Given the inherent fragility of civil war peace agreements, innovative approaches must be taken to ensure the successful resolution of these conflicts. This book provides both analytical frameworks and a series of critical case studies demonstrating the effectiveness of a range of strategies for keeping the peace. The book contends that lasting peace relies on aligning the self-interest of individuals and communities with the society-wide goal of ending war—if citizens and groups have a stake in peace, they will seek to maintain and defend it. The book's chapters explore two complementary approaches toward achieving this goal: restructuring domestic institutions and soft intervention. Some chapters examine the first tactic, which involves reforming governments that failed to prevent war, while others discuss the second, an umbrella term for a number of non-military strategies for outside actors to assist in keeping the peace.
