The fight against terrorism has been on the forefront of the U.S. and German agendas and shapes the relationship between both countries. While cooperation has been strong, differences have arisen in several areas. In Issue Brief 35, Edna Dretzka and DAAD/AICGS Fellow Stormy-Annika Mildner examine the disagreement between the U.S. and EU over sharing private financial data in relation to terrorism. The authors look at the legal situation in the United States and the political struggles in the European Union that hamper better cooperation across the Atlantic, and offer ideas on how the two actors can overcome their differences on data-sharing and SWIFT.
