Great powers, both past and present, are haunted by three interconnected preoccupations: they are tempted by a sense of national superiority and claims to manifest historic destiny. Those pretensions tend to provoke fears of decline, which then give rise to projects of rebirth.
The European empires that once fancied themselves great, most notably the British and French, are extreme examples. As France decolonised after 1945, Charles de Gaulle made “grandeur” a watchword of national policy. For the British elite, despite the increase in standards of living, decline was an obsession throughout the postwar period. Under the sign of “cool Britannia” and Tony Blair’s embrace of Europe in the 1990s, that shadow lifted. But since the banking crisis of 2008 and the Brexit referendum of 2016, the question has returned with ever-greater force. While the Brexiteers promise a “global Britain”, the average standard of living in Britain is declining for the first time in modern history. Nationalist bluster about “Britannia unchained” obfuscates a cool-eyed and practical appraisal of Britain’s actual position in the world.
