Obama has essentially ended 192 years of US policy regarding Southern America. Is this a wise move? It's certainly a shrewd foreign policy one, to take a more concilatory tone towards the United States southern neighbours, rather than the traditional 'You do as we say'.
Of course, the next president might well do a 180 on this declaration, and I dare say that the CIA isn't going to stop its missions in Southern America, but this is a big announcement to make, and I have no doubt it'll give the Republicans something to complain about.
