This core textbook is an accessible introduction to US Foreign Policy for undergraduate students. It provides a comprehensive examination of historical context and contemporary events, complete with a masterful presentation of important concepts and theoretical approaches. US Foreign Policy in a New Era has a unique emphasis on transnational issues, such as global health, the environment and terrorism, linking them together with the theme of a "web of connectivity". The author, Andrew Price-Smith, passed away soon after completing this text, and the text was finalized by a dedicated team of scholars.
