Mullen: A strike on Iran would be 'very destabilizing'

Both a US strike on Iran, and the Islamic republic attaining nuclear weapons would be "very destabilizing," chairman of the Joint Chiefs of Staff Adm. Mike Mullen said on Sunday. He called both situations "really, really bad outcomes," and urged appropriate action to prevent either eventuality. Speaking to CBS News political analyst John Dickerson on 'Face the Nation,' Mullen said that the US had a "very narrow window" of options for dealing with the Iranian nuclear threat.
