You have to add to it that Kirchnerism is going down the drain so no free foodstuffs or coke-dollars for Cuba from Buenos Aires, and Brazil is probably going to get rid of Dilma sooner rather than later and their Petrobras is in deep trouble anyway so, out of the two biggest countries in the region, one can't be bothered to worry about Cuba and the other has too many headaches to subsidise them anyway. Tourism could be a good initial bet, and Cuba could have some extra income from decently-managed (by which, incidentally, I do not mean big-foreign-firm-owned) agriculture. Are there any big fisheries around? US doesn't back down from stupid positions negotiate with terrorists and there's a very powerful pro-Cuban exile lobby. Not as powerful as the pro-Israel lobby, I think, but powerful enough. Gotten more? Step by step. Now the Cubans can't back down unless they're given an excuse. There's no one to turn if they need substantial material support in their next bout of economic crisis. Soft power can actually win at times.
