About a week ago, Iranian President Mahmoud Ahmadinejad declared to the United Nations that most people in the world believe the United States was behind the terrorist attacks of Sept. 11, 2001. Surveys show that a majority of the world does not in fact believe that the U.S. orchestrated the attacks. However, the belief persists strongly among a minority, even with U.S. allies like Turkey or in the U.S. itself. A 2006 survey by the Pew Global Attitudes Project found that significant majorities in Egypt, Indonesia, Jordan and Turkey ... said they did not believe Arabs carried out the attacks. Such beliefs have currency even in the United States. In 2006, a Scripps Howard poll of 1,010 Americans found 36 percent thought it somewhat or very likely that U.S. officials either participated in the attacks or took no action to stop them. Tod Fletcher of [WantToKnow.info] has worked as an assistant to David Ray Griffin, on books that question the Sept. 11 record. He was cautious about the Iranian president's comments about conspiracy theories, suggesting Ahmadinejad may have been politically motivated by his enmity with the U.S. government. "It seems like it's the sort of thing that could lead to further vilification of people who criticize the official account here in the United States," Fletcher said.
