Seymour Hersh on attacking Iran.

The former intelligence official added, “There is a desperate effort by Cheney et al. to bring military action to Iran as soon as possible. Meanwhile, the politicians are saying, ‘You can’t do it, because every Republican is going to be defeated, and we’re only one fact from going over the cliff in Iraq.’ But Cheney doesn’t give a rat’s ass about the Republican worries, and neither does the President.”

“They’re moving everybody to the Iran desk,” one recently retired C.I.A. official said. “They’re dragging in a lot of analysts and ramping up everything. It’s just like the fall of 2002”—the months before the invasion of Iraq, when the Iraqi Operations Group became the most important in the agency. He added, “The guys now running the Iranian program have limited direct experience with Iran. In the event of an attack, how will the Iranians react? They will react, and the Administration has not thought it all the way through.”

In interviews with current and former officials, there were repeated complaints about the paucity of reliable information. A former high-level C.I.A. official said that the intelligence about who is doing what inside Iran “is so thin that nobody even wants his name on it. This is the problem.”
