The Partnership for Peace Consortium’s Regional Stability in South East Europe Working Group aims to foster transformation in Southeast European societies and their defense and security establishments through academic research, education, training, and intensive cooperation and networking in the region and beyond. The positive practical effects over its 25 years of existence include the development of a new culture of addressing security issues in young democratic societies, evidenced by numerous academic publications, policy recommendations, and the membership of most Balkan countries in NATO and the European Union. New tasks lie ahead, and the Working Group remains committed to its mission, working closely with the Senior Advisory Council, the PfP Consortium Secretariat, and the George C. Marshall European Center for Security Studies.
