Through exhaustive use of declassified documents, previously unavailable investigative materials, and wide-ranging interviews, Malcolm Byrne explores what made the Iran-Contra scandal possible and meticulously relates how it unfolded—including clarifying minor myths about cakes, keys, bibles, diversion memos, and shredding parties. Byrne, the Deputy Director and Research Director at the National Security Archive, demonstrates that the affair could not have occurred without awareness and approval at the top levels of the US government. He reveals an unmistakable pattern of dubious behavior—including potentially illegal conduct by the president, vice president, the secretaries of state and defense, the CIA director and others—that formed the true core of the scandal.
