When Venezuela’s Mining Minister Rodolfo Sanz walked into a televised Cabinet meeting this week, President Hugo ChÁvez impishly asked, “So how’s the uranium for Iran going? For the atomic bomb.” ChÁvez was joking, but few were laughing outside Caracas and Tehran. Ever since ChÁvez announced last month that he was seeking Russia’s help to develop nuclear energy in Venezuela - and especially since Sanz turned heads a couple of weeks ago by disclosing that Iran is helping Venezuela locate its own uranium reserves - the South American nation and its socialist, anti-U.S. government have become a new focus of anxiety over regional if not global security.
