Connecting central America to the Southern Cone: the Chilean and Argentine response to the Nicaraguan Revolution of 1979

The history of the Cold War in Latin America in the 1970s is commonly split into two episodes: the establishment of anticommunist dictatorships and the ensuing repression across the Southern Cone in the early and middle decade, and the Nicaraguan Revolution and the eruption of violent conflicts across Central America at its close. By exploring the Chilean and Argentine response to the Nicaraguan Revolution, this article brings these two episodes together, demonstrating how they were understood to belong to one and the same ideological conflict. In doing so, it highlights the importance of the revolution in the Chilean and Argentine perception of the Cold War and explores how the Sandinista triumph directly shaped Southern Cone ideas about US power and the communist threat, also prompting reflection on their own ‘models’ for anticommunist governance. Both regimes responded by increasing their support for anticommunist forces in Guatemala and El Salvador, often conducting this aid through a wider transnational and clandestine network. This article contributes to new understandings of the nature of Latin American anticommunism in this period, challenges traditional understandings of external involvement in Central America, and demonstrates the need to understand events in Latin America in this period in their full regional context.
