UN peace operations have increasingly focused on the importance of “local ownership.” The logic is simple. For peace operations to succeed in helping war-torn states to create accountable, democratic institutions grounded in the rule of law, peace operations need to internalize democratic principles by making UN missions accountable to different domestic constituencies—crossing ethnic, religious, racial, social, and gender lines—within the war-torn country. As part of a special issue on “The United Nations at Seventy-Five: Looking Back to Look Forward,” this essay argues that while there is widespread consensus among UN member states and UN bureaucrats that local ownership is necessary, UN peace operations have faced significant obstacles to creating true local ownership. These obstacles include the UN's focus on host-government ownership; the challenge of creating trust with different domestic constituencies that represent diverse perspectives; the supply-driven nature of UN intervention; and the mismatch between the UN's ideal post-conflict state and the preferences of post-conflict societies. To make UN peace operations more responsive to post-conflict societies, UN staff often have to bend or break rules established only to hold them accountable to their member states.
