In regards to Iran, Hersh stated that his contacts and research points to four different groups of U.S. Special Forces being in place in Iran. A member of the audience questioned Hersh?s credibility and accused him of harboring an anti-Bush bias. Hersh replied to the written question that the articles he writes are based upon information from his contacts, many of which are very high up in the intelligence community, the Pentagon, and the government and his information usually shows up a few weeks later in the mainstream media as accepted fact. He hasn?t been wrong yet. Hersh only reveals the names of his sources when allowed to do so. Most of his contacts, however, work in intelligence and revealing their names would compromise their safety and their jobs. Hersh did say that some high-ranking Pentagon officials are very critical and upset with the Bush administration but are unable to make public comments to that effect. As far as Hersh?s comments that fighting with Iran is imminent, he was told that if he wrote the piece correctly, there wouldn?t be a fight (meaning, if he uncovered enough information and enough people read it and criticized the Bush administration, an invasion or an attack on Iran would not happen.)
