The Rise and Fall of the Great Powers. Paul Kennedy

France, first under Louis XIV and then later under Napoleon, came closer to controlling Europe than at any time before or since; but its endeavours were always held in check, in the last resort at least, by a combination of the other Great Powers. Since the cost of standing armies and national fleets had become horrendously great by the early eighteenth century, a country which could create an advanced system of banking and credit (as Britain did) enjoyed many advantages over financially backward rivals. But the factor of geographical position was also of great importance in deciding the fate of the powers in their many, and frequently changing, contests – which helps to explain why the two ‘flank’ nations of Russia and Britain had become much more important by 1815. Both retained the capacity to intervene in the struggles of west-central Europe while being geographically sheltered from them; and both expanded into the extra-European world as the eighteenth century unfolded, even as they were ensuring that the continental balance of power was upheld. Finally, by the later decades of the century, the Industrial Revolution was under way in Britain, which was to give that state an enhanced capacity both to colonize overseas and to frustrate the Napoleonic bid for European mastery.

      For an entire century after 1815, by contrast, there was a remarkable absence of lengthy coalition wars. A strategic equilibrium existed, supported by all of the leading powers in the Concert of Europe, so that no single nation was either able or willing to make a bid for dominance. The prime concerns of government in these post-1815 decades were with domestic instability and (in the case of Russia and the United States) with further expansion across their continental landmasses. This relatively stable international scene allowed the British Empire to rise to its zenith as a global power, in naval and colonial and commercial terms, and also interacted favourably with its virtual monopoly of steam-driven industrial production. By the second half of the nineteenth century, however, industrialization was spreading to certain other regions, and was beginning to tilt the international power balances from the older leading nations and toward those countries with both the resources and organization to exploit the newer means of production and technology. Already, the few major conflicts of this era – the Crimean War to some degree but more especially the American Civil War and the Franco-Prussian War – were bringing defeat upon those societies which failed to modernize their military systems, and which lacked the broad-based industrial infrastructure to support the vast armies and much more expensive and complicated weaponry now transforming the nature of war.

      As the twentieth century approached, therefore, the pace of technological change and uneven growth rates made the international system much more unstable and complex than it had been fifty years earlier. This was manifested in the frantic post-1880 jostling by the Great Powers for additional colonial territories in Africa, Asia, and the Pacific, partly for gain, partly out of a fear of being eclipsed. It also manifested itself in the increasing number of arms races, both on land and at sea, and in the creation of fixed military alliances, even in peacetime, as the various governments sought out partners for a possible future war. Behind the frequent colonial quarrels and international crises of the pre-1914 period, however, the decade-by-decade indices of economic power were pointing to even more fundamental shifts in the global balances – indeed, to the eclipse of what had been, for over three centuries, essentially a Eurocentric world system. Despite their best efforts, traditional European Great Powers like France and Austria-Hungary, and a recently united one like Italy, were falling out of the race. By contrast, the enormous, continent-wide states of the United States and Russia were moving to the forefront, and this despite the inefficiencies of the czarist state. Among the western European nations only Germany, possibly, had the muscle to force its way into the select league of the future world powers. Japan, on the other hand, was intent upon being dominant in East Asia, but not farther afield. Inevitably, then, all these changes posed considerable, and ultimately insuperable, problems for a British Empire which now found it much more difficult to defend its global interests than it had a half-century earlier.

      Although the major development of the fifty years after 1900 can thus be seen as the coming of a bipolar world, with its consequent crisis for the ‘middle’ powers (as referred in the titles of Chapters 5 and 6), this metamorphosis of the entire system was by no means a smooth one. On the contrary, the grinding, bloody mass battles of the First World War, by placing a premium upon industrial organization and national efficiency, gave imperial Germany certain advantages over the swiftly modernizing but still backward czarist Russia. Within a few months of Germany’s victory on the eastern front, however, it found itself facing defeat in the west, while its allies were similarly collapsing in the Italian, Balkan, and Near Eastern theatres of the war. Because of the late addition of American military and especially economic aid, the western alliance finally had the resources to prevail over its rival coalition. But it had been an exhausting struggle for all the original belligerents. Austria-Hungary was gone, Russia in revolution, Germany defeated; yet France, Italy, and even Britain itself had also suffered heavily in their victory. The only exceptions were Japan, which further augmented its position in the Pacific; and, of course, the United States, which by 1918 was indisputably the strongest power in the world.

      The swift post-1919 American withdrawal from foreign engagements, and the parallel Russian isolationism under the Bolshevik regime, left an international system which was more out of joint with the fundamental economic realities than perhaps at any time in the five centuries covered in this book. Britain and France, although weakened, were still at the centre of the diplomatic stage, but by the 1930s their position was being challenged by the militarized, revisionist states of Italy, Japan, and Germany – the last intent upon a much more deliberate bid for European hegemony than even in 1914. In the background, however, the United States remained by far the mightiest manufacturing nation in the world, and Stalin’s Russia was quickly transforming itself into an industrial superpower. Consequently, the dilemma for the revisionist ‘middle’ powers was that they had to expand soon if they were not to be overshadowed by the two continental giants. The dilemma for the status quo middle powers was that in fighting off the German and Japanese challenges, they would most likely weaken themselves as well. The Second World War, for all its ups and downs, essentially confirmed those apprehensions of decline. Despite spectacular early victories, the Axis nations could not in the end succeed against an imbalance of productive resources which was far greater than that of the 1914–18 war. What they did achieve was the eclipse of France and the irretrievable weakening of Britain – before they themselves were overwhelmed by superior force. By 1943, the bipolar world forecast decades earlier had finally arrived, and the military balance had once again caught up with the global distribution of economic resources.

      The last two chapters of this book examine the years in which a bipolar world did indeed seem to exist, economically, militarily, and ideologically – and was reflected at the political level by the many crises of the Cold War. The position of the United States and the USSR as powers in a class of their own also appeared to be reinforced by the arrival of nuclear weapons and long-distance delivery systems, which suggested that the strategic as well as the diplomatic landscape was now entirely different from that of 1900, let alone 1800.

      And yet the process of rise and fall among the Great Powers – of differentials in growth rates and technological change, leading to shifts in the global economic balances, which in turn gradually impinge upon the political and military balances – had not ceased. Militarily, the United States and the USSR stayed in the forefront as the 1960s gave way to the 1970s and 1980s. Indeed, because they both interpreted international problems in bipolar, and often Manichean, terms, their rivalry has driven them into an ever-escalating arms race which no other powers feel capable of matching. Over the same few decades, however, the global productive balances have been altering faster than ever before. The Third World’s share of total manufacturing output and GNP, depressed to an all-time low in the decade after 1945, has steadily expanded since that time. Europe has recovered from its wartime batterings and, in the form of the European Economic Community, has become the world’s largest trading unit. The People’s Republic of China is leaping forward at an impressive rate. Japan’s postwar economic growth has been so phenomenal that, according to some measures, it recently overtook Russia in total GNP. By contrast, both the American and Russian growth rates have become more sluggish, and their shares of global production and wealth have shrunk dramatically since the 1960s. Leaving aside all the smaller nations, therefore, it is plain that there already exists a multipolar
