7 most controversial UN speeches, from Ahmadinejad to Khrushchev

5. Hugo Chavez, Venezuelan president, 2006

In a speech warning the UN body about the dangers of imperialism, Venezuelan President Hugo Chavez claimed that American imperialism "puts at risk the very survival of the human species." Lest anyone remain unconvinced, he recommended Noam Chomsky's book, "Hegemony or Survival: America's Quest for Global Dominance."

The most infamous moment, though, came a little later in the speech, when he repeatedly compared Bush to the devil. "In this very place, it still smells of sulfur," he said. "Yesterday, ladies, gentlemen, from this same rostrum, the president of the United States, who I call the devil, came here talking as the owner of the world."
