Providing an in-depth study of the construction of foreign policy in developing countries, Martin Mullins takes an original line of both a post-positivist methodology and an acceptance of the importance of the realism in foreign policy formation in the Southern Cone countries from the early 1980s to the present day. This carefully constructed work highlights the case of Chilean foreign policy in the 1990s in order to examine the adoption of realism in its policy formation, in contrast to the strong historical narratives of Argentina and Brazil. The volume focuses on the nuances of foreign policy making through a comprehensive study of political culture that underlines the links between domestic and foreign policy sets in the region.
