The U.S. doesn't maintain any sort of blockade against Cuba. Ships and airplanes from countries other than the U.S. are free to come and go from Cuba as they please and many do, with no interference from the U.S. military.

The U.S. maintains a trade embargo such that U.S. citizens and corporations cannot legally do business with Cuba. The nationals of most other countries, Canada for instance, can do business with Cuba as they please. This is in no way similar to the naval blockade of Gaza maintained by Israel, where any and all vessels and aircraft, even ones in international waters, are prevented by military force from even declaring Gaza as a destination and virtually all cargo items are arbitrarily declared to be of military value.

You're thinking, no doubt, of the 1962 Cuba Missile Crisis, in which the U.S. enforced a quarantine against Cuba of offensive military equipment. This was actually done under the auspices of the Organization of American States, not as a unilateral U.S. action, and it was quite selective for military hardware. Normal trade was not disrupted beyond inspection of cargoes and the action lasted only a few weeks, not the decades you claim.

Gene, I know you to be an honest and honorable person. You have no need to use tactics of conflation and redefinition like some Fox news personality.
