The Report from Iron Mountain

The Report from Iron Mountain is a book published in 1967 (during the Lyndon B Johnson Administration) by Dial Press which puts itself forth as the report of a government panel. The book includes the claim it was authored by a Special Study Group of fifteen men whose identities were to remain secret and that it was not intended to be made public. It details the analyses of a government panel which concludes that war, or a credible substitute for war, is necessary if governments are to maintain power. The book was a New York Times bestseller and has been translated into fifteen languages. Controversy still swirls over whether the book was a satiric hoax about think-tank logic and writing style or the product of a secret government panel. The document is a favorite among conspiracy theorists, who seem unaware that in 1972 the satirist Leonard Lewin admitted the book was a spoof and that he was its author.
