The irony is that the neocons are the TRUE isolationists. The neocons wish to isolate and forbid trade with regimes that they disapprove of. The neocon policy toward Cuba is the very definition of isolationism.
For over half a century, we’ve had an embargo with Cuba. Not only did the Castros survive it, but they milked it for everything it was worth. The Cuban government stoked the flames of nationalism in Cuba and blamed America for anything that went wrong, rather than the true culprit—their own dogmatic socialism.
The isolationist neocons want to continue this embargo. They want to peel back the small diplomatic gains that have been made. They want to pare back cultural exchange and dialogue.
The opposite, free travel and trade, is what is needed.
