The main brake lies in the sort of relationship existing between North American diplomats and the Cuban civil society.
Thus wrote this Tuesday a journalist from the French agency AFP, Alexandre Grosbois, repeated by the New Herald in Miami.
It would be necessary to begin clarifying what does this society mean for Washington?
So far a group that includes groups fully developed in the island for many years to which they have openly given generous amounts of money.
Some of them grew really angry some time ago with the former senator John Kerry because he hindered the delivery of 20 million dollars for their actions against Cuba.
What was the pretext? Fighting for democracy and the human rights under the parasol of official institutions of the North American government.
Among them, as an example, their Agency for International Development USAID.
As it’s known, that entity has been expelled from several countries due to the services they give to the CIA.
Cuba denounced before the First World Conference of Internet about seven months ago the use in its territory of information technologies and communications with subversive purposes.
Among those deeply involved appeared the USAID, mother of the secret program Zunzuneo, a.k.a. the Cuban Twiter.
But the most brutal expression in the behavior of the U.S. Interests Office in Havana is in short Mr. James Cason.
He wrote a dirty history since in September 2002 the republican president George W. Bush, so far-right as ignorant, put that office in his hands.
There is one event, among so many, that summarizes his work, it took place on July 4, 2005 and was reported by the New Herald and news agencies.
Back then, on Independence Day of the United States, he gathered in the gardens outside his residence the heads of the "dissident" groups to celebrate that day.
He also orchestrated in those diplomatic grounds a charade of elections at the same time and day that took place in the United States.
This along with the long chain of provocative declarations and concrete actions of open subversion.
Late last May, on the eves of the new meeting between both governments, a Cuban official declared that it is pending to solve "the régime of diplomats’ movement".
And he added, "Plus his behavior", an idea related to his work regarding the so-called promotion of democracy.
The aforementioned AFP journalist, Alexandre Grosbois, commented that that activity angers Havana, later he explained the reason why.
To achieve this goal he turned to Marc Hanson, from the center Washington Office for Latin America (WOLA).
In Cuba, - asserted the expert - "those activists have a tendency to be working or acting in the opposition to the Cuban government".
Grosbois adds that, despite everything, the North American mission offers Cuban internet access and "training at their own headquarters or at the official residences".
Later on he remembers that President Raul Castro noticed that the reopening of a North American embassy won't be possible until the rectification of certain "behaviors."
“I spoke the president (Barack Obama) concretely about what worried me the most is that (the North American diplomats) keep doing the illegal activities they have done up to now", like the training to "independent journalists, either at the Interest Office or at the diplomats' houses".
The AFP correspondent, Grosbois, added another quote from the words of the Cuban leader:
"Those things can’t be done. Simply, what we say is that we all must stick to the agreements on the behavior of diplomats, approved in the Vienna Convention of 1961."
Alexandre Grosbois dared saying, the day the Interest Office becomes an embassy, and it would be very delicate to justify this sort of activities.
