Parodi shows that boundary disputes have and continue to play a major role in creating tensions in South America. Of the 25 international territorial boundaries that exist in South America, eight were marked with major wars, eight with lesser wars, and five with some level of violence. As recently as 1995, the armies of Ecuador and Peru were at war to define a boundary. In 1982 Argentina went to war, inspired by the call to restore a piece of its mutilated national territory. Venezuela and Guyana, Guyana and Suriname, and Suriname and French Guiana have not completed boundary demarcation agreements. Bolivia's insistence on its right for sovereign access to the Pacific Ocean is a source of tension with Chile and Peru. Colombia and Venezuela have unresolved boundary issues in the Gulf of Venezuela. Clearly, boundary disputes have and continue to play a major role in creating larger conflicts within South America. Territorial boundaries are marks on the ground, but, as Parodi shows, their staying power or stability depends on their grip on consciousness. By examining the boundary theory of South American states and its implementation, he also explains how the symbolic system of South American boundaries is used to instill national identity, mobilize people to war, and control population and territory. This text will be of particular interest to scholars, students, and researchers involved with Latin American politics, diplomacy, and international relations.
