The untold story of how Lisa Howard’s intimate diplomacy with Cuba’s revolutionary leader changed the course of the Cold War.

Fidel Castro, the fiery apostle of revolution who brought the Cold War to the Western Hemisphere in 1959 and then defied the United States for nearly half a century as Cuba’s maximum leader, bedeviling 11 American presidents and briefly pushing the world to the brink of nuclear war, died on Friday. He was 90.

The story of William Morgan: American, wanderer, Cuban revolutionary.

“Let me state, in all frankness, that I have never harbored personal doubts or a lack of confidence. That may be good or it may be bad. But if you see your actions as objectively correct, then not having doubts is good. I must admit that pride may have influenced my attitudes from time to time. But once I came to a conclusion as to what was right, I had great personal confidence in those ideas.”

On the ground to witness Cuba’s last days:

“Either we rectify our course or the time for teetering along on the brink runs out and we go down. And we will go down…[with] the effort of entire generations.”—Raul Castro
