I'm surprised at this take. It seems readily apparent that Cuban exiles want their countrymen and women to be free from state communist control and have the ability to speak their mind, practice economic freedom and their religion, which is I understand is very Catholic from Spanish influences. I don't know how you can say Cuban exiles want the people they left behind to suffer.
I am saying that because the sanctions haven't achieved anything positive for the last decades. At some point people just have to admit that they don't work but cause a lot of suffering. I bet if the US traded with Cuba, the communist regime would quickly fall apart like the Eastern block did.
