I thank the right hon. Gentleman for the generous way in which he asked his question. Precisely because of that destabilising approach to many parts of the most dangerous and unstable region in the world, although we do not agree with the US approach to the Iran nuclear deal, we do try to support the US in every way when it asks us to help—for example, in checking the activities of Hezbollah in Lebanon. We have proscribed Hezbollah in this country, because we do think that it is a terrorist organisation, and we have to recognise that in British law.
The same is true of the work that we do with the American military in Syria, Iraq and Yemen. Our approach to Yemen has been to try to separate the Houthis from their Iranian paymasters. Although we might not agree with the tactics, it is important that we recognise that in the United States strategic approach, the long-term solution in the region is for Iran to cease that destabilising activity.
