USIP supported the work of Marc Chernick, Visiting Associate Professor and MALAS (Master of Arts in Latin American Studies) Director at Georgetown University’s Center for Latin American Studies, in producing the book Acuerdo Posible: solución negociada al conflicto armado colombiano (Bogota: Ediciones Aurora) in 2008. This book provides a comprehensive history and analysis of the political violence in Colombia from 1946 until the present and examines the achievements and failures of a series of peace processes between the Colombian government and leftist guerillas that took place over a 20-year period. The book examines the impact of the drug trade, the role of the international community, the changing perceptions of the causes of political violence as well as the changing geopolitical framing of the conflict through the prisms of the Cold War, the war on drugs, and the war on terror. The book examines key proposals and negotiating strategies implemented by both sides in the different historical and political junctures.
