Trump has essentially reversed the good things that President Obama did towards Cuba. I believe this is a highly misguided policy.
The Europeans are already doing business with Cuba, this keeps American farmers, and American companies from being a part of the growth of Cuba.
It will not get the Castro’s to change one idea they already have in place regarding human rights.
It will, however, effect Cuban Americans that have been enjoying the more open policy, with the ability to visit and help their families to a greater degree than before.
It will also cut tourism back, hurting hotels that have started to invest in Cuba, and airlines that had spent billions of dollars purchasing the airline routes.
