U.S. international interests rest on a triad of three Ds—Defense, Diplomacy, and Development. They are co-equal in policy statements, not in practice. Defense dominates in the budget arena. Diplomacy dominates at the policy level. Development too often has been the afterthought and not preeminent even in its own space. If it is to fulfill its role in advancing U.S. international interests, the American approach to development needs an upgrade in structure and resources.
