When China Rules the World

Military and political power rest on economic strength. As Paul Kennedy argued in The Rise and Fall of the Great Powers, the ability of nations to exercise and sustain global hegemony has ultimately depended on their productive capacity. [16] America’s present superpower status is a product of its rapid economic growth between 1870 and 1950 and the fact that during the second half of the twentieth century it was the world’s largest and often most dynamic economy. This economic strength underpinned and made possible its astonishing political, cultural and military power from 1945 onwards. According to the economic historian Angus Maddison, the US economy accounted for 8.8 per cent of global GDP in 1870. There then followed a spectacular period of growth during which the proportion rose to 18.9 per cent in 1913 and 27.3 per cent in 1950. This was followed by a slow and steady decline to 22.1 per cent in 1973, with the figure now hovering around 20 per cent. [17] This still represents a formidable proportion, given that the US accounts for only 4.6 per cent of the world’s population, but the long-run trend is unmistakable. [18] One could make a similar point in relation to Victorian Britain’s imperial reach between 1850 and 1914. This was made possible because Britain accomplished the world’s first industrial revolution and, as a consequence, came to enjoy a big economic lead over all other countries. Compared with the United States, however, whose share of global GDP peaked at 35 per cent in 1944 (albeit in a war-ravaged world), the highest figure for the UK was a much smaller 9 per cent in 1899. The precipitous decline of Britain as a global power over the last half century has been the predictable result of its deteriorating relative economic position, its share of global GDP having sunk to a mere 3.3 per cent by 1998. [19] If Britain took its place alongside the United States in Iraq, its military contribution was largely cosmetic. The precondition for being a hegemonic power, including the ability or otherwise to preside over a formal or informal empire, is economic strength. In the long run at least, it is a merciless measure. Notwithstanding this, imperial powers in decline are almost invariably in denial of the fact. That was the case with Britain from 1918 onwards and, to judge by the behaviour of the Bush administration (though perhaps not Obama’s) – which failed to read the runes, preferring to believe that the US was about to rule the world in a new American century when the country was actually in decline and on the eve of a world in which it would find its authority considerably diminished – the US may well make the same mistake, perhaps on a much grander scale. The financial meltdown in 2008 belatedly persuaded a growing number of American commentators that the United States might after all be in decline, but that was still a far cry from a general recognition of the extent and irreversibility of that decline and how it might diminish American power and influence in the future.
