I totally agree with the comments that my noble friend has made. I read the strategic defence review again over the weekend in preparing for the Question, so I know that it is chapter 6. The important part was the challenge that it makes—not only to the public but to us as politicians and to Parliament—to reflect on how we engage. Too often, when we talk about national conversations, we talk about having a village hall meeting here or a village hall meeting there. That is not sufficient. This requires a whole-government approach, involving all government departments, the devolved Governments, local authorities, civil society, financial society and industry. All those together need to wake up to the very real threat. As my noble friend says, we are facing a threat now, not in a year’s time or five years’ time. That threat is upon us, and we need to wake up to it.
