Back in 1967, a book was published called Report from Iron Mountain. It put forth the claim that "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 author of the book's introduction, Leonard Lewin, later claimed that the book was a hoax. But conspiracy factualists didn't buy his claim. Guess who was right? Or perhaps this is just another one of those amazing "coincidences" that a secret (not any more) government facility bears the same name as a controversial book on the government.
By the way, I've often seen trucks with the Iron Mountain logo on the street. I never thought much about them (i.e., that there was a connection with the book) until I watched this video and saw the same logo at the Iron Mountain facility being reported on in this video. Perhaps this is an example of the government "hiding in plain sight."
