I have the feeling that plans are being made for the turn over and that Raul is not the communist that his brother thought him to be.
I think that he will be extremely practical and that will lead to substantial change.
"Substantial" should be spelled $ubstantial.
Cuba will try to go the Chinese route of going for the $$ while reserving the right to run you over with a tank when they feel you are getting too "uppity"
Without a cleansing of the communists (a.k.a. socialists in a hurry) from Cuban politics and government there will be no change.
We need Nuremberg style trials for those in power and to treat the communists like the Germans treated the Nazi cancer that infected their country.
