The good governance of military and security forces is essential for the effective defense of a nation or alliance and for fostering their democratic evolution. This article explores NATO and partner countries’ initiatives over the past three decades to enhance good governance, distinguishing five waves of focus: civil-military relations and democratic control of armed forces, defense institution building, security sector reform, building integrity and reducing corruption, and strengthening democratic resilience. The authors review the research and educational activities of the Partnership for Peace Consortium and other organizations in support of these initiatives, concluding with a proposal to establish a working group on democratic resilience within the Consortium.
