In the Introduction, the co-editors of the work, Bertha García Gallegos and José Manuel Ugarte, present the fundamental aspects of the book, highlighting that it carries out an analysis of civil-military relations in Latin America, including both common aspects shared across the region and the specific characteristics observed in the seven countries—Argentina, Brazil, Chile, Colombia, Ecuador, Uruguay, and Venezuela—that serve as case studies. The co-editors pointed out that, in addition to considering the political, sociological, and legal aspects of the issue, they found it necessary to analyze its historical aspects, which they consider a fundamentally important for understanding the topic, along with the influence of external powers and the prevailing international environment. They also pointed out the importance of civil-military relations for the consolidation and strengthening of the democratic system, noting that, despite the time elapsed since their independence, all Latin American countries should be considered in transition toward the full realization of that system—albeit to varying degrees—and that one of the main reasons for Latin America has not achieved a level of democratic development comparable to that of younger countries, such as India and Israel, lies in these relations. They also stressed that, among the types of civil control identified by Huntington in his classic work “The Soldier and the State,” they clearly considered objective civil control as preferable. In Latin America, they noted that cases of subjective civil control, such as that of Venezuela under Hugo Chávez and Nicolás Maduro, the attempt in Ecuador by Colonel Lucio Gutiérrez, and Evo Morales in Bolivia, had, for various reasons, failed to contribute to the strengthening of democracy in their respective countries. They emphasized that efforts to align the Armed Forces with a certain political sector have been detrimental to democracy in the region.
