Hezbollah in Latin America? Impossible

A few years ago, I spent time in Argentina and Paraguay, specifically in Ciudad del Este, where the Hezbollah presence seemed quite obvious and open. After I reported on this phenomenon, various and sundry Hezbollah apologists said that Hezbollah couldn't be active in Latin America, without providing many reasons why, apart from the usual reason that Hezbollah is not a terrorist group but a social service agency. So I suppose that this latest report can't be true, either.
