Peacebuilding is an interactive process that involves collaboration between peacebuilders and the victorious elites of a postwar society. While one of the most prominent assumptions of the peacebuilding literature asserts that the interests of domestic elites and peacebuilders coincide, Costly Democracy contends that they rarely align. It reveals that, while domestic elites in postwar societies may desire the resources that peacebuilders can bring, they are often less eager to adopt democracy, believing that democratic reforms may endanger their substantive interests. The book offers comparative analyses of recent cases of peacebuilding to deepen understanding of postwar democratization and better explain why peacebuilding missions often bring peace—but seldom democracy—to war-torn countries.
