John F. Kennedys assassination launched a frantic search to find his killers, as well as a flurry of covert actions by Lyndon Johnson, Robert F. Kennedy, and other top officials to hide the fact that in November 1963 the United States was on the brink of invading Cuba, as part of a JFK-authorized coup. The coup plans exposure could have led to a nuclear confrontation with Russia, but the cover-up prevented a full investigation into Kennedys assassination, a legacy of secrecy that would impact American politics and foreign policy for the next forty-five years. It also allowed two men who confessed their roles in JFKs murder to be involved in the assassination of Dr. Martin Luther King in 1968. Exclusive interviews and newly declassified files document in chilling detail how three mob bosses were able to prevent the truth from coming to lightuntil now.
