This text helps students understand the context of headline events in the international arena. Organized into three main parts--military, economic, and human security--the book's fifteen cases examine enduring and emerging issues from the longstanding Arab-Israeli conflict to the rapidly changing field of cyber-security. Compatible with a variety of theoretical perspectives, the cases consider a dispute's origins, issue development, and resolution so that readers see the underlying dynamics of state behaviour and can try their hand at applying theory.
