He also maintained that any intervention in Iraq should have been through the United Nations.
Asked about these remarks on Thursday, Mr Chirac added: "If you observe the way things are developing in the world in terms of security and the expansion of terrorism - not just in the Middle East but throughout the world - if you look at all that, you cannot say - and be credible - that the situation has significantly improved."
