This project is concerned with the effects of the American decision to withdraw from the nuclear agreement with Iran, negotiated and signed by a variety of international actors, on relations between Europe and the United States. Primarily through an examination of speeches by European leaders, this project explores the nexus between discourse, policy, and its implications for the future of trans-Atlantic diplomacy. It is found that the implications for American withdrawal are far reaching, overwhelmingly negative, and appear to result in increasing alienation and reduced allignment between Europe and the United States.
