Peacebuilding actors — from nongovernmental organizations to diplomats and security forces — tend to work concurrently but are often unable to integrate their efforts around a single process or framework. The Principles for Peace Initiative seeks to create a shared language for peacebuilding actors so that peace efforts can overcome these silos. Roméo Dallaire, a Canadian Forces lieutenant-general and former senator who led the U.N. peacekeeping force for Rwanda from 1993-1994, discusses the Principles for Peace; how he has applied them to his work to end the use of child soldiers; and why transparency is critical for overcoming the ethical, moral and legal challenges of peacebuilding.
