"Due to extensive cooperation on a wide range of issues, the relationship between the United States and Europe is often called the transatlantic partnership. The two sides have many common values and concerns, and have grown increasingly interdependent in terms of security and prosperity. The transatlantic relationship and the main areas of U.S.-European cooperation and shared interest are likely to have continuing implications for U.S. policy during the 114th Congress. Members of Congress may have an interest in considering the dimensions and dynamics of current issues in U.S.-European relations in the course of oversight or legislative activities, or in the context of direct interactions with European legislators and officials. According to most observers, the overall tone of transatlantic relations during the Obama Administration has been largely positive. At the same time, a constructive tone does not necessarily translate into tangible results with regard to foreign policy objectives or other goals. With respect to certain issues, U.S. and European policies have been at odds and have generated friction in the relationship from time to time. This report summarizes key issues that both illustrate the nature of U.S.-European cooperation based on shared interests and present challenges in terms of the efficacy of such cooperation… […] As the United States and Europe face a changing geopolitical environment, some observers assert that the global influence of the Euro-Atlantic partnership is in decline. In addition, the Obama Administration's announced intention of 're-balancing' U.S. foreign policy toward Asia has caused some anxiety among Europeans."
