Abstract
The cases of peacemaking in Kosovo and Sudan/South Sudan yield insights into the interplay of international politics, relations among political elites, and reconciliation among identity groups. A durable, positive peace requires an approach by peacemakers that encompasses all these dimensions. Complicating matters, the readiness of states to adhere to rules and norms built up over decades has declined in recent years. Absent a concerted effort to (re)build them, the work of peace mediation will become more challenging and the odds of success incalculably longer. This, in turn, will corrode the ability of external powers, competing via proxy, to work together even on unrelated matters in different parts of the globe.
