This second edition of a successful book has been updated and extended and, as its predecessor did, presents students with an essential and concise introduction to postwar US foreign policy. This book explores the key questions of who makes policy, why, in what style or tradition, under what kinds of democratic controls and in what kind of international environment. Updated to include recent developments in US foreign policy, and with expanded chapters, this new edition provides challenging and thought-provoking analysis of the crucial issues, including: the accession of George W. Bush; September 11th and the recent war in Iraq; containment; presidential war powers; realism and idealism; the Cuban missile crisis; Vietnam, Panama, Yugoslavia and Kosovo; the New World Order; and, US interventionism and exit strategies. With a student-friendly chronology, expanded referencing, and a new conclusion that unites the themes of the book and looks toward the future, this will undoubtedly be as widely-used and popular as the excellent first edition.
