My right hon. Friend is right, and of course the short answer is that we keep on going, because the consequences of a confrontation leading to a conflict in the middle east involving Iran and others would be catastrophic. We will continue with our efforts. We have sanctions against elements in Iran. There are the economic sanctions employed by the United States and others, but we have to keep looking for a way in which we end the risk of a serious confrontation in the middle east. It is not to be encouraged by harsh rhetoric on either side, and I think that the United Kingdom’s diplomatic efforts to try to bring some resolution in the area are the best thing that we can do.
