Jorge Castañeda has an unusual article in Newsweek. The core of his argument is that Cuba is so incredibly powerful that we need to end the embargo. He concludes:
Havana and Chávez are closely aligned; Zelaya would never have made it to the Brazilian Embassy in the Honduran capital without Cuban logistical aid, and Chávez himself would probably not survive politically or otherwise without the island's security apparatus that permanently surrounds him. But an end to the embargo could begin to split apart Havana and Caracas, and it is probably the only intelligent policy Washington has available to it.
I have to say that I've not heard this argued before. Hugo Chávez would not survive politically without Cuba? Fidel and Raúl orchestrated Mel Zelaya's return? Neither Roberto Micheletti nor Jim DeMint has even gone that far!
On other hand, I support ending the embargo for a number of reasons, so I will try to overlook the odd rationale people might have for agreeing with me.
