A sunken Soviet submarine. A secret CIA plan to lift it from the bottom of the ocean with a giant claw. And reclusive billionaire Howard Hughes. It sounds like the makings of a Netflix series--and it should be. But the story of the Glomar Explorer is the stuff of fact, even if it has long been shrouded in secrecy.  

In his new book, intelligence historian M. Todd Bennett pierces the veil surrounding this most improbable of intelligence operations and surfaces a riveting tale of underwater espionage and high-stakes foreign policy. The sub-salvage mission, which the CIA codenamed AZORIAN, was greenlit at a time of remarkable daring and ingenuity by the spy agency, which enjoyed only minimal oversight from Congress. But journalists brought the Glomar operation to light in another era, when scandals and excesses led lawmakers to reign in the intelligence community.  

Shane Harris talks with Bennett about his book, Neither Confirm nor Deny: How the Glomar Mission Shielded the CIA from Transparency, which shows how the exposure of the secret program led to a public backlash against disclosures of classified information and helped reenforce the culture of secrecy that envelops the CIA’s work. The phrase “neither confirm nor deny,” which Bennett tells Harris has become a kind of coy cliche, originates from attempts to uncover the facts of the Glomar mission.
