One hopes, as man usually does, this will not be screwed up with violence breaking out between Castro's brother Raul into whose leadership Cuba has been entrusted and those who want to overthrow him on the right. Will the US help them along? Who knows? It would NOT surprise me if the CIA sends in the drones to lend an assist. Stay tuned! Think Bay of Pigs II.
A bit of irony Trump writing uncomplimentary words, of course, about Castro when he went against the law to develop businesses in Cuba which was illegal at the time. According to the September 28, 2016 Daily News: "The "Castro Connection" story claims Trump spent at least $68,000 in 1998 for a business foray into Cuba — even though any corporate activity in the Caribbean country was completely illegal without government approval at the time."
How about the DOZENS of right wing dictatorships the US supported for which often the US was behind a coup -- Example Allende in Chile much loved leader duly elected in Chile but replaced by CIA nefarious activity installing Pinochet a brutal military dictatorship and killer of anyone who opposed him.
Oh yes, there was the Iran Contra affair where Oliver North tried to overthrow the Nicaraguan Sandanistas sanctioned by Reagan going against the Boland Amendment prohibiting such acts. No problem, just pardon them all!
Ted Cruz, Tom Cotton, Donald Trump where are your words of condemnation for the many right wing military dictatorships the US supported if not singularly tried to create through coups and overthrows. I remember US history. Please do not forget the United Fruit Co. Per Wiki:
"The 1954 Guatemalan coup d'état was a covert operation carried out by the United States Central Intelligence Agency (CIA) that deposed the democratically elected Guatemalan President Jacobo Árbenz and ended the Guatemalan Revolution. Code-named Operation PBSUCCESS, it installed the military dictatorship of Carlos Castillo Armas, the first in a series of U.S.-backed dictators who ruled Guatemala."
