You gotta read this at Accuracy in Media. David Landau writes a few home truths. First and foremost, he points out the obsession the embargo lifters seem to have with Cuba. That we should be accused of obsession is understandable, but why these perverse individuals can't leave Cuba alone is unfathomable.
The most important part of the article is the withering denunciation of the regime, and indirectly of those who would do business with it:
Decades of history have now shown the bitter fruits of Castro’s rule. In all that time, the U.S. embargo has achieved exactly what it set out to do. It has simply stated, for everyone to hear, that Americans do not wish to have trade with Cuba’s overlords and slave-masters.
It is such a clear, and concise statement of the rationale for not lifting the embargo that it should be reprinted everywhere.
