Normalization of relations with Cuba is not the result of a diplomatic breakthrough or a change of heart on the part of Washington. Normalization is a result of US corporations seeking profit opportunities in Cuba, such as developing broadband Internet markets in Cuba.
Before the American left and the Cuban government find happiness in the normalization, they should consider that with normalization comes American money and a US Embassy. The American money will take over the Cuban economy. The embassy will be a home for CIA operatives to subvert the Cuban government. The embassy will provide a base from which the US can establish NGOs whose gullible members can be called to street protest at the right time, as in Kiev, and the embassy will make it possible for Washington to groom a new set of political leaders.
In short, normalization of relations means regime change in Cuba. Soon Cuba will be another of Washington’s vassal states.
