Now fully revised and updated, this accessible and astute text provides a full interpretive history of the transatlantic alliance and explores critical developments in US-European relations. Stanley R. Sloan considers the ongoing pattern of US unilateralism and its consequences as the transatlantic and intra-European debate over Iraq produces deep splits among the allies and seriously erodes European trust in US leadership. Ironically, at the same time, the United States and Europe have made historic choices concerning NATO's future, not only continuing the process of enlarging alliance membership but also expanding NATO's missions to include peacekeeping and enforcement without geographic limitation. Sloan also builds on his ideas for a new Euro-Atlantic pact, a call that has now been echoing in both European and American quarters. Assessing both the good and bad news for the alliance, this book remains a central text for college and university courses on US-European relations and transatlantic security issues, and offers thought- provoking reading for all citizens concerned about future US foreign policy and Europe's role in it.
