Retired US Navy Lt. Commander and ONI officer Al Martin wrote "The Conspirators: Secrets of an Iran-Contra Insider."
In this book, Martin explains the operations of the Bush Cabal and details the many Iran-Contra-related criminal operations involving Robert Gates, currently the Defense Secretary designate.
In terms of policy management, (William) Casey formed a series of inter-governmental agency Restricted Access Groups (RAGs). Ultimately three such groups were formed. The top Restricted Access Group 1 was Vice President George Bush -- as it was decided that all narcotics, weapons and money operations vis-à-vis Iran-Contra, would be consolidated under the office of the Vice President.
Also included in these Restricted Access Groups were then Vice Presidential National Security Advisor, Colonel Donald Gregg, then Deputy Secretary of State Lawrence Eagleburger and Assistant Secretary of State Elliott Abrams, who was in charge of the Inter-American Affairs Office (an office which served in no other capacity except being a propaganda tool for the Nicaraguan Contras), Richard Armitage, and Assistant Secretary of State, Bernie Aronson.
