Need we the people say much else? The United States of America has punished the Cuban people long enough. It is clear that your strategy of causing civil unrest by way of sanction is a miserable failure. We the people demand trade and tourism with and to Cuba, the beautiful and historic gem of the Caribbean.
We the people do not want to hear "it's complicated", it's not. One does not punish a child for their parent's crimes. Stop vetoing UN resolutions to this effect, open the door to our friendly and culturally vibrant people to the immediate south. If your intention is still to topple Castro et al... Supposed human rights abuses are not unique in this hemisphere.
In any case, the foolishness has gone on long enough, the pros outweigh the cons.
