I am generally in favor of the policy of an opening to Cuba, but ...
For those of you who are not acquainted with the universally accepted standards of diplomatic and government to government courtesy, a visiting official should be met at the point of debarkation by his/her counterpart. To do less than that is understood to be a gesture of disrespect.
The president of the United States is both Head of State and Head of Government. It would have been appropriate and respectful for the president of Cuba to meet him at the airport. The Foreign Minister of Cuba is in no way the protocol equivalent of the president of the United States. In my opinion Obama should have told the foreign minister that he would wait aboard Air Force One for an hour for Raul Castro's arrival planeside. Failing that arrival, a return to the US would have been appropriate for our delegation.
And then there was the moment in which Raul Castro attempted to hold Obama's arm up as though he were a prizefighter or some other ridiculous thing.
Does the Cuban government really want détente with the US? If so they had better clean up their act. pl
