About

The Transatlantic Security Initiative’s mission is to contribute to a strong and resilient transatlantic relationship that is prepared to deter and defend, succeed in strategic competition, and harness emerging capabilities to address future threats and opportunities. This mission endures across changing political dynamics on both sides of the Atlantic and in the face of new and evolving threats.

TSI advances the interests and values of the United States and its transatlantic allies and partners through the Atlantic Council’s convening power, our cutting-edge research and substantive expertise, and through our extensive and influential network across the transatlantic community. We work in partnership with governments, the private sector, think tank community, academia and others. We hold expert public and private convenings, conduct research, organize study trips, and produce publications, commentary and analysis to shape and influence policy and debate on the biggest challenges facing the transatlantic relationship. Intellectual independence is a cornerstone of our work at all times.
