To study international politics since the turn of the century has been, in large part, to study the changing nature of autocracy – and the West’s relationship to it. We kicked things off by trying to realise the Trotskyite dream of ushering in global democracy through the barrel of a gun. We wanted to bring an end to the world’s tyrants – or the ones of relevance to us at any rate. We got Iraq. But if we failed to end tyrants, we played our part in helping to mould them. As Sergei Guriev and Daniel Treisman observe in their intelligent, important book Spin Dictators, throughout this time something far more interesting and dangerous was happening. The most sophisticated dictators were reforming themselves, and the lesson they internalised was not the need to be democratic – that, after all, went against who they were – but the need to look democratic.
