... I do not think that there is any doubt that Fidel Castro, as a symbol of revolt in this hemisphere, has faded badly. Every survey, every report, I think every newspaperman, every publisher, would agree that because Mr. Castro has embraced the Soviet Union and made Cuba its satellite, that the appeal that he had in the late fifties and early sixties as a national revolutionary has been so badly damaged and scarred that as a symbol, his torch is flickering. We have not been successful in removing Mr. Castro. We should realize that that task is one which involves not only the security of the United States, but other countries. It involves possibilities of war. It involves danger to people as far away as West Berlin, Germany, countries which border upon the Soviet Union in the Middle East, all the countries that are linked to us in alliance, as the Soviet Union is so intimately linked with Cuba.
So we have attempted to isolate Cuba in the hope that some day Cuba will be free and that the pressures of life in Cuba will make it more obvious to people around this hemisphere that communism does not offer a shortcut to economic well-being. The gross national product of Cuba is 25 percent below what it was in 1958. The Soviet Union today is giving $450 million worth of assistance every year to Cuba. They are pouring into Cuba--and this should be a source of concern to us, because Latin America is still before us, and the challenge of Latin America--they are giving as much aid to Cuba alone as we are giving to all of Latin America. That is not a statistic in which I take particular pride, but it does indicate how heavy is their commitment and how successful so far has been their support.
Some Soviet troops still remain, not as armed units. There has been a substantial withdrawal, but there is a good deal of unfinished business in Cuba.
In answer to your question, Mr. Castro still is in control in Cuba, and still remains a major danger to the United States.
JFK tried very hard to kill Castro. See the Church Committee report.
Trump violated the embargo.
