Mark Eric Williams 
Understanding U.S.-Latin American Relations [PDF ebook] 
Theory and History

This book examines U.S.-Latin American relations from an historical, contemporary, and theoretical perspective. By drawing examples from the distant and more recent past-and interweaving history with theory-Williams illustrates the enduring principles of International Relations theory and provides students the conceptual tools to make sense of inter-American relations. It is a masterful guide for how to organize facts, think systematically about issues, weigh competing explanations, and confidently draw your own conclusions regarding the past, present, and future of international politics in the region.
