Watch the Miami speech by JFK that I uploaded--JFK publicly vowed, in that speech made in December of 1962, after the CMC, that the Cuban exiles' flag would fly over a "Free Havana."
The Kennedy brothers were working several levers through 1963, from Castro assassination plots, to fomenting internal divisions in Cuba. They were hard core on Cuba. They were again developing more-substantive plans, while curtailing rogue amateur-ops by Cuban exiles All that stopped suddenly with JFK's assassination.
LBJ curiously lost interest, seemingly entirely, in Cuba. And there it has stood since.
Interesting topic.
Well, let us hope Trump-Rubio can win the day this time around.
A Free Cuba, and a Free Iran, would be tremendous accomplishments.
