Fidel Castro by his own admission has been a communist since 17, despite what uninformed people write on the internet, he was not "forced into the Soviet sphere" by the US embargo. Rather, the US was one of the first countries to recognize his government after the revolution, and Castro was given a ticker-tape parade in NYC. As always happens after such revolutions, Castro was unable to live up to his Utopian promises. In order to hold power, he suspended human rights. During the heyday of the Soviet Bloc, Cuba had the most repressive laws of any communist country. Habeas Corpus doesn't exist in Cuba. Under laws enacted by Castro, people can be imprisoned indefinitely, even executed, if they have an "appearance" that suggests they may do something immoral. In the 60s, Castro sent people to slave-labor camps for listening to the Beatles, now there's a statue of John Lennon in Havana, why? Because Castro needs green dollars to continue his regime, and Americans & Europeans like to get their picture taken at the statue so they can look cool. Unless something in Cuba is related to tourism or foreign dollars, it is left to rot and crumble.
Twenty percent of Cubans are in prison or exile.
Fidel Castro is a billionaire, and if you support him, you are what HE CALLS a "useful idiot".
