The Transatlantic Defense and Security program at CEPA shapes policy debates, builds communities of interest, and develops innovative policy solutions to the 21st century’s most pressing transatlantic security issues. Our goal is to ensure the United States and its closest allies can maintain their strategic edge in an increasingly contested world. We focus on strengthening Euro-Atlantic institutions, promoting US engagement in European security, and deepening transatlantic cooperation. We bring a forward-looking approach to our analysis, with insight formed across generations, backgrounds, and borders. By bringing together key stakeholders, pioneering new ideas, and publishing substantive content, we help governments, businesses, institutions, and the public understand and navigate today’s uncertain security environment.
