Using a three-part framework of Ideas, Arguments, and Contexts and Applications, International Relations, Third Edition, shows students how to think critically about issues and current events in world politics. Each chapter first describes key concepts and developments in the field (Ideas), then presents the main theoretical and analytical approaches (Arguments), and finally applies the main theories and approaches within the individual, state, and global contexts (Contexts and Applications). In additional to historical information woven throughout the text, the book also includes a new separate chapter on history (Chapter 2) that summarizes key events and includes an illustrated timeline. A new Chapter 11 focuses on the future of International Relations and Chapter 8 has been updated and expanded to cover non-state threats and international security. Theory is now covered in two chapters–one focused on classical theories (realism and liberalism)–and the other on contemporary theories and perspectives (constructivism, Marxism, feminism, rational choice). Visual Reviews at the end of each chapter not only recap key points but include Critical Thinking questions that reflect the chapter learning objectives.
