Well, I wondered in this place last week if David Cameron knew what he was doing in relation to the Iran nuclear negotiations in Geneva. And now the answer is clearly, ‘no’.

America and Europe’s overwhelming desire to declare a deal meant that there had to be a deal to declare. The P5+1 countries, with the ludicrous Catherine Ashton speaking for Europe, have indeed made a historic and terrible mistake.

The mullahs did not come to Geneva because they wished to give up their capability. And they did not come to the table because after 34 years of revolutionary Islamic governance they have seen the error of their ways. They came because international sanctions were beginning to hurt. Those sanctions – which took years to put in place – have now fallen apart thanks to a few days of incompetent negotiating on the part of the P5+1 plus some simple common sense from Tehran. People tend to say at this stage that the Iranians are ‘master negotiators’. They aren’t especially. They are simply fortunate to be playing against Catherine Ashton and a generation of other weak and short-sighted American and British politicians.

The result is that the Iranian regime has managed to walk away with a deal to relieve the pressure of sanctions at the very moment that the pressure was working and the very moment that it should have been kept up and ultimately used to break them. They now have the breathing hole they need to reinforce their power at home and continue their search for nuclear weaponry.

At the root of this debacle is the fact that the Iranians went into the sanctions knowing exactly what they wanted: time and the bomb. The P5+1 countries, by contrast, were riddled by doubt and muddled thinking.

There should only ever have been two aims with regard to the Iranian regime. The first is to ensure that it never ever gains the capability to develop nuclear weapons: not only to ensure that the world’s most destabilising regime never possesses the world’s most dangerous weaponry, but to ensure that it cannot precipitate a nuclear arms race across the Middle East.

The second aim, and one which appears to have slipped even further down any international agenda, is to see the end of the brutal rule of the mullahs. Sadly this does not even appear to be on the table any more. Ever since President Obama failed to come out in support of the brave Iranian protestors who rose up in 2009, the basic human rights of the Iranian people have been ignored utterly. So what that the regime promotes terror around the world? So what that it oppresses, rapes, tortures and executes its opponents at home? By negotiating with this regime and allowing it off the hook at this moment America, Britain and our allies have not only given a stay of execution to the mullahs, we have further undermined the hopes of any opponents of the regime inside Iran.

I was watching and listening to William Hague earlier today and I must say that it was a pathetic experience: a diminished figure trying to persuade a sceptical nation to support a demeaning deal. All he lacked was a winged collar, a piece of paper and the slogan: ‘nuclear peace in our time.’
