This course provides an introduction to the study and analysis of both the history and the evolution of the security policy sphere. This policy sphere is defined in a broad sense—from nation states, to guerrillas and insurgencies, to organized crime, gangs, traffickers, that is, all enemies of the state. The main lens of analysis is the study of the multiple strategies that the US has implemented to confront the evolving conflict and security challenges in Latin America: some debatably successful like Plan Colombia, and others less so, such as the interventions in Nicaragua. The lack of economic opportunity, rampant corruption, weak rule of law and fragile government institutions continue to riddle Latin America and serve as migration factors. Newer initiatives such as the Merida Initiative, the Central American Regional Security Initiative (CARSI) and the Alliance for Prosperity are also analyzed to learn from the past and the present to address shortfalls and potential solutions in a region beleaguered by insecurity and violence, in spite of the absence of international wars.
