National Security Archive Electronic Briefing Book No. 283: “The Central Intelligence Agency participated in every aspect of the wars in Indochina, political and military, according to newly declassified CIA histories. The six volumes of formerly secret histories (the Agency’s belated response to a Freedom of Information Act (FOIA) request by National Security Archive senior fellow John Prados) document CIA activities in South and North Vietnam, Laos, and Cambodia in unprecedented detail. The histories contain a great deal of new material and shed light on aspects of the CIA’s work that were not well known or were poorly understood.”
