'Tall odds' against Iran nuclear deal
President Bush's former National Security Advisor, Stephen Hadley, supports a military strike against Iran if talks fail and the Islamic Republic moves towards developing a nuclear weapon.
Mr Hadley sounds sceptical that a satisfactory deal can be reached. He says this isn't the deal many had expected - too many compromises have already been made.
The man who advised President Bush on foreign policy from 2005 to 2009 - at the height of the Iraq war violence - also seems to think that negotiating during the current Middle East meltdown is difficult if not impossible.
