Robert David Steele, former Marine, CIA case officer, and US co-founder of the US Marine Corps intelligence activity, is ... widely recognised as the leader of the Open Source Intelligence (OSINT) paradigm. In 1992, despite opposition from the CIA, he obtained Marine Corps permission to organise a landmark international conference on open source intelligence - the paradigm of deriving information to support policy decisions not through secret activities, but from open public sources available to all. The conference was such a success it brought in over 620 attendees from the intelligence world. But the CIA ... ensured that Steele was prohibited from running a second conference, [prompting] him to resign from his position as second-ranking civilian in Marine Corps intelligence. Last month, Steele presented a startling paper at the Libtech conference in New York. Drawing on principles set out in his latest book, The Open-Source Everything Manifesto ... he told the audience that all the major preconditions for revolution - set out in his 1976 graduate thesis - were now present in the United States and Britain. Steele's book ... connects up the increasing corruption, inefficiency and unaccountability of the intelligence system and its political and financial masters with escalating inequalities and environmental crises. But he also offers a comprehensive vision of hope. "Sharing, not secrecy, is the means by which we ... can create a nonzero win-win Earth that works for one hundred percent of humanity."
