The reality of nuclear combat's devastation was clear as soon as the first atomic weapons were dropped during World War II, leading the U.S. government to develop a "doomsday plan"out of perceived necessity. In the Cold War era, the threat of impending nuclear warfare – and the fear it caused in the American citizenship – escalated even further. Politicians played on this fear, and the government began planning for a potential attack. Testing bombs on mock cities in the Nevada desert – constructed to assess potential damage – was only part of the doomsday strategy. The U.S. also secretly dug giant bunkers into mountains, allegedly to protect the American way of life.
Only through a fluke was one of these hollowed-out mountains, the Raven Rock complex, discovered by journalist Gerrett Graff. His investigation into the elaborate compound yielded some surprising finds.
