Transatlantic Security

Within Transatlantic Security

The United States is safer, more prosperous, and more influential in the world when it cooperates and coordinates with its European allies and partners. The mission of the Transatlantic Security Program is to help decision-makers understand, anticipate, and respond to the shared challenges and opportunities that the allies face. In doing so, the Transatlantic Security Program aims to contribute to a stronger and more cohesive transatlantic partnership.

Given Russia’s full-scale invasion of Ukraine, the Transatlantic Security Program is focused on anticipating the trajectory of the war, identifying recommendations for how the United States and Europe can support Ukraine, and understanding how the nature of the Russian threat is evolving and how the allies can most effectively respond. Our program also examines how Russia’s war in Ukraine is changing political dynamics well beyond Ukraine, including the implications of NATO’s expansion as well as the deepening partnership between Russia, China, North Korea, and Iran.

Given the complexity of the current international system, the United States and Europe must also navigate other pressing challenges such as China’s rise; threats to democracy, including those that stem from within our own systems; and the role of technology in the transatlantic relationship.

To address these and other issues, the Transatlantic Security Program works closely with our network of current and former U.S. and European government officials, private sector partners, and academic experts to translate cutting edge research into policy solutions. We foster high-level U.S.-European dialogue, including through our flagship Transatlantic Forum on Russia; convene seminars and public forums; and host discussions on TSP’s Brussels Sprouts podcast to shape the context in which policies are made.
