My hon. Friend makes an important point. Every UN resolution on the question of Iran's nuclear weapons capacity that has been proposed and passed talks about a middle east that is free of nuclear weapons. As a result, it is simply untrue for the Iranians to say, as they sometimes attempt to do, that we are not playing on a level playing field when it comes to our response to their nuclear weapons capacity. We should remember that this is not just about the threat to the stability of the middle east that would be posed by Iran developing nuclear weapons. The arms race that would be triggered in the region would be like nothing we have ever seen before, and that is why it is so crucial that we stop Iran developing nuclear weapons.
