Fostering Diplomatic-DefenseDevelopment (3D) Cooperation in Responding to Complex Crises

The US diplomatic, defense, and development communities (known as the “3Ds”) increasingly find themselves working together to tackle complex crises. This collaboration has already proved its worth, but how can it be made even more effective? A recent USIP research project sought to answer that question by examining 3D collaboration in Jordan, Burma, and the Lake Chad region. This Peace Brief distills the findings of those three case studies and presents a list of five steps the US government can take to enhance the ability of the State Department, Department of Defense, and USAID to respond to complex crises.
