He [Osama] called for a worldwide boycott of American goods and the dollar. He faulted the United States for failing to sign the Kyoto Protocol, which sought to curb global warming by restricting greenhouse gas emissions. And he offered a word of praise for Noam Chomsky, the American linguist and liberal political activist.

“Noam Chomsky was correct when he compared the U.S. policies to those of the Mafia,” Al Jazeera quoted Mr. bin Laden as saying. “They are the true terrorists and therefore we should refrain from dealing in the U.S. dollar and should try to get rid of this currency as early as possible.”

“Talk about climate change is not an ideological luxury but a reality,” Mr. bin Laden was quoted as saying in a report on Al Jazeera’s English-language Web site. “All of the industrialized countries, especially the big ones, bear responsibility for the global warming crisis.”
