Francesca Lessa and Sebastián Santana, "Operation Condor: The Pact That Terrorized a Continent" (Storia, 2025) – New Books in National Security

In Operation Condor: The Pact That Terrorized a Continent (Storia, 2025), Francesca Lessa uncovers the shadowy machinery behind one of the most chilling transnational terror campaigns of the twentieth century. What began as a secret pact among South America's military dictatorships quickly grew into a coordinated system of surveillance, kidnappings, torture, and disappearances that reached across borders and oceans. Through meticulous research and newly unearthed documents, Lessa reveals how those in power built a network designed to eliminate dissent wherever it dared to surface, turning exile into a false refuge and entire nations into hunting grounds. This book is not simply a reconstruction of clandestine meetings and sealed orders, though it excels at that. It is a deeply human story that follows the lives interrupted and the families who refused to surrender to silence. Lessa brings to light parents who never stopped searching, survivors who fought to be heard, and investigators who chipped away at decades of denial. Their voices and struggles give this history its pulse, reminding us that truth is often preserved not by institutions but by ordinary people who refuse to forget. Translated with clarity and grace by Alejandro Reyes, and enriched by Sebastián Santana Camargo's haunting illustrations, this authorized English edition of the acclaimed Plan Cóndor: Viejos secretos y nuevos hallazgos is both a work of history and an act of witness. It confronts a past many hoped would remain in the shadows and insists on remembering, not out of vengeance, but as a defense of democracy and dignity. The result is a gripping, sobering, and ultimately hopeful testament to the enduring power of memory and justice. Learn more about your ad choices.
