The debate internationally on the conditions for peace and for sustaining peacebuilding has been characterized by a considerable degree of conceptual confusion and theoretical disagreements. There is a great need for clarification – or even a need to find common ground to avoid gratuitous or rhetorical differences and to search for more broadly perceived practical recommendations. Although policy makers and practitioners may not ordinarily benefit from theoretical debates among academics, especially if conceptualization is quite abstract, the assumptions and conclusions of these debates can and often do affect public discourses.
