The message of the Cuban Revolution for a generation of young Latin American leftists was to put aside reformist politics and take up arms. North Korea vowed to support all those who heeded that call. Its intervention came at a time when many young radicals sought a personal transformation, one that would allow them to participate in the crucial historical juncture they believed themselves to be living through. Hundreds, possibly thousands, of Latin American militants sought this transformation in secret training camps in North Korea, with the hope of returning to their home countries new subjects, with the physical and mental attributes necessary to make revolution. Between 1964 and 1970, North Korea provided military training to at least nine revolutionary groups in seven Latin American countries: Venezuela, Colombia, the Dominican Republic, Peru, Brazil, Guatemala, and Mexico. This chapter provides an in-depth overview and assessment of North Korea’s efforts to support revolutionary struggle in Latin America.
