Thanks for the link to the bio. That is some story!
Well worth the time to read... His Father-in-Law, Ray Cline was Deputy Director of the CIA.
And in 1962, as the head of the directorate of intelligence, the agency’s analytical branch, Ray Cline was among those who concluded that the Russians had installed offensive-missile bases in Cuba, and carried the news to President John F. Kennedy. Nuclear war was narrowly averted when Kennedy and the Soviet Premier, Nikita S. Khrushchev, reached an agreement that provided for the dismantling of the missiles.
Thirty years afterward, Mr. Cline, who grew a somewhat unruly beard later in life, stood whisker to whisker with Fidel Castro at a conference of historians in Havana and joked with the Cuban leader about the C.I.A.’s clumsy efforts to assassinate him in the 1960’s.
