Would that the Cold War-era relationship between Cuba and the United States were merely an embarrassing, time-warp tete-a-tete. Hardly the case, as we are routinely reminded with those one-sided United Nations votes against the U.S.-imposed embargo on Cuba. Another example: the recent gathering of the Community of Latin American and Caribbean States in Santiago, Chile. The newly-elected chairman: Raul Castro. Among interested outside parties: a delegation of European leaders led by German Chancellor Angela Merkel. The theme wasn’t isolation.
