Outside the Base at Guantanamo Bay last week, the US Military and Cuban Frontier Brigade worked together in basic preparation for major disasters. This is not a new collaboration, but the Obama Administration opted to make the exercise public, in contrast to the previous Bush policy of keeping it secret. According to US Marine Corps General Jack Sheehan, the preparations are yet another sign of an “Incremental process” towards more cooperation. ''We've never advertised [the exercise]… because it was very controversial,'' he said. The Administration seems to be sending yet another “trial balloon,” with this announcement, following the talks on migration last week in New York.
