International regimes for the management of inter- and intra-state conflict only work when they can operate in a stable regional security environment. International mediators can have the most skillful negotiators, the most credible ‘honest-brokers’, the most attractive incentives for peaceful reconciliation, and the most sophisticated political institutions for power sharing, but they are unlikely to succeed without the determined support of Great Powers and so long as there are other powerful actors in the region who encourage one side or the other to resort to violence. Moreover, this is an enduring feature of international relations; it was as true during the interwar period as it is now that the Cold War has ended. Security is a nested condition that policymakers and diplomats create from the outside-in and not from the inside-out.
