Preparing a new introduction of his Iron Britannia, Anthony Barnett is appalled at how relevant the book has become after 30 years. The combined impact of the 2008 financial crash and its economic consequences, alongside defeats in Iraq and Afghanistan, expose once again the foundations of Britain’s peculiar political culture, which was the main focus of the original 1982 edition. A vivid account of the start of his own political journey becomes a sober warning for the future: they will do it again if they can unless the ‘Great’ is taken out of Britain.
