Just a thought, but do you think maybe Obama and Company may be thinking if part of the deal to normalization of diplomatic ties with Cuba, is to turn over Gitmo?
The timing of Rauls mentioning this, at this time, raises a couple of serious questions.
If it was preplanned, it would explain the rush to empty the facility of prisoners before turning it over. And the insistence in transferring them to the US for trial. Because Castro doesn't want them along with the deal.
Or if the facility can't be closed by any other means, it would force the closure, and transfer of prisoners, to meet Obama's desire to get them back into the battle field before he leaves office.
