My hon. Friend touches on quite a deep issue that reflects his knowledge and expertise in this area, to which I pay tribute. I spent some of the summer reading the works of Gertrude Bell, which I know he has studied. She illustrates, and learned over a long period, the complexity that we are dealing with in today’s Saudi Arabia. We have to understand and recognise that it is a conservative society which is being obliged and encouraged to move at a far faster pace than many other countries in the world, not least in the legitimacy of running a complex and sustained campaign of war.
