U.S. Marines in Haiti. Pirates or drug traffickers penetrating the southern border of the United States. Special economic arrangements that foster growth for some and hardship for others. These headlines about the Caribbean's international relations and its impact on the United States could date from both the beginning and the end of the twentieth century. Troubled as it is, the Caribbean nonetheless features important accomplishments that will benefit the United States in the long term. This book examines the crucial and timeless impact Caribbean countries have on the United States and the world, and the methods they have been employing to consolidate their democracies, advance prosperity, and maintain the peace through international cooperation among themselves. Its primary aim is to discuss the dominant threat perceptions and security priorities of regional governments, the varied mechanisms in place to promote regional collective action, and the future agenda of U.S. foreign policy toward the Caribbean. Rooted in an historical analysis of continuity and change in the Caribbean's international subsystem, the book analyzes the Caribbean within a broader international pattern, marking a tension in world affairs between the global and the local. In addition, it explores the challenges to governments and peoples in the region posed by changes in its political economy.
