Here's an incomplete, incompetent translation of Hugo Chavez's remarks at the UN General Assembly. Here's a more complete, competent one. Just compare the first few lines and you'll notice significant differences, including the Chomsky references.
The press in the US, and Democrats like Pelosi too, are villifying Chavez for his "sulfur" remark. I for one found it amusing, as did several of the delegates to the UN, who could be heard laughing in the background. And if you read the entire text of the well-presented translation you'll see that the sulphur references, in context, are solidly metaphorical, speaking of the stench of the demon who'd spoken from that podium the day before.
