I didn’t think there was anything wrong with the Cuba policy.
I don’t have too many issues with it either.
But consider for minute...
In the late 1980’s we were engaged with the USSR and the other Warsaw Pact countries. As they saw how badly they were lagging behind the western nations and technology made access to western media more available, the communist governments fell in months.
The preconditions for that had been going for years and were made possible by the fact that there was limited contact and economic ties between the West and Eastern Europe. We may have missed a chance with Cuba 25-30 years for the same thing to happen. Its just something I wonder about from time to time.
