This updated edition examines Hoover’s career in detail, and looks at his role in the development of the Cold War against Communism. With considerable detail and an excellent selection of photographs, Kiel traces Hoover’s anti-communism to his earliest experiences, during WW I. Well- documented and thought provoking, this study looks at the connections between Hoover, Lyndon Johnson, the assassination of President John Kennedy, and the escalation of the Vietnam War. In Kiel’s updated New Conclusion (2025), the author adds new photographs of a number of witnesses to JFK’s assassination that Kiel has interviewed, new information relating to the recent release of the JFK files as well as a number of other important topics. These topics include: New Research on Mr. Hoover, A Closer Look at Hoover’s Connections With Organized Crime, Lyndon Johnson and Bobby Baker, Jack Ruby Revisited, Lee Oswald an FBI/CIA Informant, The 6th Floor of the Book Depository--Who Was Actually There?, The Zapruder Film, The Changes in JFK’s Motorcade and Protection, Lee Bowers - Was he the Most Important Witness?, Looking Back at the ARRB and the CIA, Attempts to tie up Loose Ends, and Final Thoughts on the Legacy of President John F. Kennedy.
