Designed to complement the main themes of any introductory course, Snow’s bestselling text presents original case studies that survey the state of the international system and look in-depth at issues of current interest. The cases are extremely timely, geopolitically diverse, accessibly written, and of high interest and salience amidst today’s headlines. Examples include the Islamic State’s violent quest for religious sovereignty in Syria and Iraq, Russian oil and U.S.-Russian relations, North Korea and nuclear weapons, multilateral solutions towards peace, international trade, and international migration.
