From the 14 Jan Economist: When the Soft Talk Has to Stop
A Shortlist of Options
The first step will be to convene an emergency meeting of the IAEA's board, likely later this month, to receive a formal report about what Iran has been up to. America has long pressed for Iran to be referred to the United Nations Security Council for its actions. Short of an about-face by Iran, the Europeans will now press hard for that outcome. A majority on the IAEA's board already favours referral. But for Iran to take notice, Russia, China and others will have to back the idea too. Both countries have been loth to lean hard on Iran in the past. But both are bitterly disappointed that its regime has upped the ante in this way.

Getting to the council is one thing; getting action from it is another. A presidential statement urging Iran to comply with inspectors' requests, and even assigning the IAEA wider investigative powers, might get through, since the point would be to strengthen the inspectors' hands, not take Iran's case away from them. Beyond that, other steps could include political sanctions, such as denial of visas for sporting teams or for members of Iran's regime (similar actions are thought to have helped in the past in dealing with the recalcitrant Serb government, for example). Unlike the North Koreans, who seem not to mind their isolation, Iranians take pride in their growing contacts around the world and are keen to be accorded the status and respect they feel their ancient civilisation deserves. That said, however, Iran's new president, eager to wipe Israel off the map, seems dangerously unfazed by world opinion (see article).

It would be tougher to win widespread support at the UN for economic sanctions. Several key countries, including Russia (which also recently signed a $1 billion weapons contract with Iran), China, India and Japan have been reluctant to put their oil and gas contracts and their pipeline projects at risk. Yet such targeted sanctions might be the one thing that could get Iran's full attention. Its energy industry is dependent on foreign investment for future expansion and modernisation. Meanwhile, India is an important supplier of refined petrol to Iran.

The Europeans have already hinted that if sanctions are blocked at the UN, they will impose their own. They will also try to get others to join them, rather as America has orchestrated the Proliferation Security Initiative, an informal posse of countries prepared to take tough action to block shipments of illicit goods and materials around the world related to weapons of mass destruction.

The Last Resort
Might force be the answer? Mr Bush has always said that no option is off the table. Israel says Iran must not be allowed to develop nuclear weapons and has suggested that, once Iran has mastered enrichment, perhaps as early as a few months from now, its nuclear programme will have passed “the point of no return”. Might either government be tempted to pre-empt the diplomacy with military strikes?

Israel's air force flattened Iraq's Osiraq nuclear reactor in 1981. But Iran has learnt from that episode. It has dispersed, hidden and buried its numerous facilities; some sites, including Natanz, are up to 75 feet underground. Nor is sabotage much of an option. Ploys such as assassinating Iranian nuclear scientists or infecting Iranian computer systems with viruses would cause minimal damage. And yet there are military options, however imperfect and risky.

Only America could hope to demolish Iran's programme. The Iranians are believed to have, in addition to its main sites, at least a score with a role in the programme, and more than 100 sites suspected of having a role. To attack them all, with cruise missiles and fighter-bombers, would require an extended campaign and hundreds of sorties. Corridors would have to be cleared through Iran's air defences and the Iranian air force destroyed. Collateral damage, to Iranian civilians and cities, could be extensive.

A likelier alternative might be to launch an attritional campaign by attacking Natanz and Bushehr, recognising that the resulting damage would at best delay Iran's nuclear progress. This is certainly the most that Israel could contemplate unilaterally. Such an attack would be a declaration of a war which Israel could start but might not be able to finish without American protection. And Israeli fighter-bombers would find it hard to reach Iran without passing through American-controlled airspace.

To attack Iran this way would make sense only if it were thought likely that a friendlier Iranian regime would then emerge. But Iran has no obvious, friendly government-in-waiting. And Iran could strike back—by closing the oil chokepoint of the Strait of Hormuz or hitting American or Israeli interests via proxies in Saudi Arabia, Iraq, Lebanon and the occupied West Bank and Gaza. Israel is well within range of Iranian missiles. Diplomacy has not stopped Iran so far. But military action is by no means an attractive alternative.
