This study examines the experience of the United Nations interventions to reform Haiti’s security sector as part of a larger effort to rebuild the Haitian state. Despite multilateral attempts in the 1990s to demobilize the army, create a police force and implement reforms, the lack of elite support, insufficient judicial sector capacity and persistence of corruption led to the current resurgence of violence. The study concludes that a legitimate national dialogue with local elites, and long-term donor involvement, specifically of the United Nations, are necessary to ensure that justice, security, development and the governance sector are developed simultaneously to prevent Haiti from becoming a failed state.
