Fidel Castro's message to President Johnson (February 12, 1964): "If the president feels it is necessary during the campaign to make bellicose statements about Cuba or even to take some hostile action - if he inform me, unofficially, that a specific action is required because of domestic political considerations, I shall understand and not take any serious retaliatory actions."
"Tell the President, I realize fully the need of absolute secrecy... I revealed nothing at that time ... I have revealed nothing since... I would reveal nothing now"
