Building peaceful nation-states which respond to the aspirations of their citizens takes strong leadership, both international and domestic. The international community has an important role to play in assisting countries to avoid, contain and recover from conflict, and the recent past demonstrates how much can be achieved when global and national incentives align, and program implementation is appropriately designed and well-managed. Too often, though, efforts have failed to decisively address the motives and opportunities which help to mobilize violent conflict; to integrate political, security and development approaches; or to align local, national, regional and global actions. As a result, some areas have seen new waves of conflict and violence in recent years and some “post-conflict countries” have not yet managed to make a decisive shift to successful and stable development.
