We have moved far past the point being to “prevent the threat of a good example”. That might have been the case 25-30 or more years ago, but now the only point is to appease the large number of wealthy ex-Cubans and their descendants. And yes, ex-Cubans, not Cuban Refugees. You don’t get to call yourself a refugee for 50+ years, at a certain point you have to accept that you have abandoned your country and embraced another. There’s nothing wrong with that, but you aren’t a refugee.
