Transformative peace operations fall short of achieving the modern political order sought in post-conflict countries because the interventions themselves empower post-conflict elites intent on forging a neopatrimonial political order.

Barma's comparative analysis of interventions in Cambodia, East Timor, and Afghanistan focuses on the incentives motivating domestic elites over a sequence of three peacebuilding phases: the elite peace settlement, the transitional governance period, and the aftermath of intervention.
