On Foreign Policy: Travel restraints after Cuban missile crisis kept until 1977

There was a justified concern, during a brief period more than 4 decades ago, when President John Kennedy was informed that Soviet missiles were being sent to Cuba, and the "Cuban missile crisis" was properly named. Since then, the continued fixation on Cuba has become ludicrous and counterproductive. A punitive embargo has been imposed on the already suffering Cuban people, the freedom of our own citizens to visit and trade with Cuba has been curtailed, and cultural and humanitarian cooperation has been outlawed. The only tangible results of this policy have been to hurt the people of Cuba and turn them against the US.

With the missile crisis resolved, in 1977 I removed all travel restraints.
