What is working and showing good results need to be kept in place. Establishing normal trade relationship with Cuba will only empower the current tyranny more and will delay even more the time when the people will come to the final decision of becoming bullet bags in their fight for freedom, as it happened in Romania and other ex communist countries. Once the spark is set on an decades long accumulation of explosive and volatile environment, there is no stopping it. While Cuba was protected by the Soviet Union, Cuba was a dangerous revolution exporter in the destabilized and vulnerable nations of the world (remember Angola and Grenada) and a destabilizing factor through communist propaganda (look at Venezuela, Bolivia, Ecuador and other countries). Once Cuba is liberated, the whole communist move in South America will die or retreat in the jungles to form terrorist groups. Cuba WILL be free, and in great measure, thanks to the American embargo.
