Keith Olbermann talks with Sy Hersh, the award-winning investigative journalist, about the intensifying sabre rattling from Bush, Cheney and the Neocons toward Iran. Hersh claims his sources are telling him that Bush is not only changing targets in Iran, but also the reasons for attacking. Hersh also asserts the intelligence community is very concerned about the threat of asymmetrical warfare in the aftermath of any sort of strategic strike within Iran, and that the Bush regime has been made aware of those concerns.
