With a mix of research methodologies applied by scholars from both sides of the Atlantic, Turbulence Across the Sea offers a comprehensive analysis of relations among European and North American actors in the context of strategic competition among the United States, Europe, Russia, and China. In doing so, it demonstrates that a reaffirmation of transatlantic cooperation is necessary to maintain security in the face of aggressive moves by both Russia and China. By analyzing attitudes from the perspective of both the various actors (Britain, France, Germany, and the European Union) and various sectors (intelligence cooperation, foreign direct investments, technology, and the defense industry), this book provides readers with a comprehensive understanding of the challenges and opportunities in the shifting landscape of security in the twenty-first century.
