LONDON, England (CNN) -- French Foreign Minister Bernard Kouchner's declaration that France had to prepare for the possibility of war against Iran over its nuclear program was not conventional diplomatic behavior. But then Kouchner was never expected to be a soft-soaper on the diplomatic scene.
French foreign minister Bernard Kouchner has a reputation for challenging convention and authority.
A surprise appointment from the Socialist ranks to Nicolas Sarkozy's conservative government, the founder of Medicins Sans Frontiers has always challenged convention and authority.
The former UN Secretary General Boutros Boutros-Ghali once called Kouchner 'an unguided missile' and the man himself has been known to declare: "To change the law you sometimes have to break the law". He was in his youth one of the leaders of the students revolt in France in May 1968.
Kouchner is a humanitarian as well as a patriot, with a strong commitment to human rights. Unusually for a man of the Left, he supported the US-led intervention in Iraq (while criticizing the aftermath). But he did so on the grounds of Saddam Hussein's denial of human rights, not his possible possession of weapons of mass destruction. His and President Sarkozy's concern for human rights lies behind their eagerness to join Gordon Brown's Britain in a new push for action in Darfur.
Bernard Kouchner did not come to his position with any of former President Chirac's instinctive distrust of the United States. Washington, which has been critical of some European states for their weakness in confronting Teheran, will have been delighted by his 'get serious' warning to Teheran. But the plain-speaking Kouchner is unlikely to be deterred by fears of upsetting the White House when he has criticisms to make of US policy.
How much should be made of his words on Iran remains unclear at this stage. They were scarcely on the same scale as President Chirac's threat when he was still in office to retaliate with nuclear strikes against any state found to be responsible for a large-scale terrorist attack on France. But they are all of a piece with France's new high-profile style under the presidency of Nicolas Sarkozy.
Mr Kouchner, for example, became the first French Foreign Minister to visit Iraq since 1988, insisting that there could only be a political solution to the country's problems, not a military one, and offering France's services as a mediator and 'honest broker' between Sunnis, Shiites and Kurds.
On Iran he is, in a way, merely echoing the words of his President who declared in a speech last month that a nuclear-armed Iran would be 'unacceptable' and describing the stand-off over its nuclear program as 'undoubtedly the most serious crisis before us today'. Certainly Mr Kouchner is making clear that France no longer takes the view once expressed by President Chirac that a nuclear-armed Iran might be inevitable
In continuing to ratchet up the rhetoric over that threat and to underline the West's resolution on Iran's nuclear enrichment program Mr Kouchner is supplementing his president's warnings. Neither is saying that military intervention against Iran is imminent or inevitable. Neither has yet confirmed that France would be part of any such military action. But both are stressing the risks which are piling up as a result of Teheran's brinkmanship.
Perhaps the strongest lesson though from Mr Kouchner's intervention is his underlining that the new administration in France is not a knee-jerk anti-American one -- and that France is in the business of reclaiming a role at the top diplomatic tables. E-mail to a friend
