The authors examine the utility of the U.S. Government's whole-of-government (WoG) approach for responding to the challenging security demands of operations in Iraq and Afghanistan. They specifically discuss the strategic objectives of interagency cooperation particularly in the areas of peacebuilding and conflict management. Discussions range from the conceptual to the practical, with a focus on the challenges and desirability of interagency cooperation in international interventions. Shared were experiences and expertise on the need for and future of an American grand strategy in an era characterized by increasingly complex security challenges and shrinking budgets. All agreed that taking the status quo for granted was a major obstacle to developing a successful grand strategy and that government, the military, international and nongovernmental organizations, and the private sector are all called on to contribute their best talents and efforts to joint global peace and security efforts.
