 So I think that's a question that really characterised much of the 20-year campaign. And one of the things I've reflected on a lot since leaving Kabul, since leaving the Foreign Office, and I think one of the benefits that I bring to this discussion now is the ability to ask exactly that question. So we're dealing with really big first-order problems of this nature. How do we support decision-makers to deal with the facts as they are rather than as they would like them to be?
