Two important studies have been published this autumn on the apparent failure of our almost 20-year war in Afghanistan. In the Times Literary Supplement my friend Rory Stewart has been reviewing The Afghanistan Papers by Craig Whitlock; and last week I went along to the launch at the Frontline Club in Paddington of the BBC correspondent David Loyn’s The Long War, my copy of which has just arrived. Both look like brilliant accounts of what went wrong, both will surely prove useful guides to a lamentable episode in modern statecraft, but both — and Rory too in his own TLS assessment and recommendations — appear to me to be missing the point. These three writers have become so close, so engaged, for so long, to a knot of truly Gordian complexity, that they have missed the Gordian solution.
