It was revealed by the Associated Press on October 15, 1984. The ninety-page book of instructions focused mainly on how "Armed Propaganda Teams" could build political support in Nicaragua for the Contra cause through deceit, intimidation, and violence. The manual also discussed assassinations.The ICJ case Nicaragua v. United States found that the publication of this manual had "encouraged acts … contrary to general principles of humanitarian law." However, the CIA claimed that the purpose of the manual was to "moderate" the extreme violence already being used by the Contras.
