This volume examines the foreign policy transition from George W. Bush to Barack H. Obama in relation to the countries of the Americas. In this work, contributors consider the major defining features of their respective policies in dealing with security-related issues. Specifically, they examine whether major differences or continuities truly exist between the foreign policies of Bush and Obama, especially given the perception of American decline. The volume highlights Obama's foreign policy in the Americas, focusing on issue areas that threaten international security, such as drug trafficking, organized crime, and terrorism. This work provides both theoretical and policy insights for academics and policy analysts interested in foreign affairs.
