Easing up on Cuba in any way, makes absolutely no sense! There may be some very special interests that would profit (Belo Corp. that owns the Dallas newspaper seems to be such a company) , but anything that helps Castro enslave the Cubans makes no sense at all. Further, it is my view that Castro is leasing bases to Saudi and Al-Qaeda terrorists who are sent to Mexico and then released into the US in small groups. When Fidelito is gone, fine, we'll revisit the issue. But, while he is alive and in charge, there is NOTHING that speaks for this.
Of course, the efficiencies of Castro's criminal justice system do seem to be desireable (end of trial to execution in six days) and, maybe, that is what the neocommunists see.
