Global conflicts are becoming increasingly transnational and often involve non‐state actors. These trends mirror the diffusion of power that has resulted from globalization and the erosion of liberal hegemony since the late 1990s and early 2000s. Though projections vary among scholars, the future international system is likely to involve a diversification of actors exerting influence in all policy spheres, including conflict‐response and peace operations. The United Nations (UN) and other liberal actors, historically dominant in peace operations, must adapt to remain relevant in a future where their governance of operations, and the underlying liberal democratic goals on which they are based, can no longer be assumed. In light of this waning liberal international order, this paper examines the core lessons learned from the past 70 years of UN peace operations to infer what future UN peacekeeping might look like and what adaptations will be necessary for this new environment. In so doing, we prepare recommendations for a truly localized and contextualized approach to peace operations that is expansive, representative and non‐directive, ultimately necessitating the UN and other liberal actors to adopt higher risk tolerance and relinquish exclusive control over conflict‐response and peace.
