Transatlantic relations are undergoing a fundamental period of transformation and redefinition. The United States and Europe find themselves in a G-20 world: Can they reconcile European integration with a reorientation of transatlantic relations to forge a more effective strategic partnership that addresses global challenges? The Center for Transatlantic Relations and a consortium of American and European think tank experts, high-level practitioners, and scholars examine U.S. and EU approaches to a wide range of topics, from economic and financial governance, justice affairs, and human rights to bilateral security cooperation, energy and climate change, and issues of transatlantic homeland security and resilience. They offer a number of specific proposals for a more effective transatlantic partnership in a global age.
