The great revolution which began about 1750 and has increased in breadth and depth throughout the past two centuries had led to vital changes in structure and functioning, particularly of the West but generally in the entirety of human society. So far-reaching are these changes, and so deep running, that human society, particularly in the West, has outgrown or is outgrowing the life pattern evolved by civilizations during the past four or five millenia. As a consequence, geographical expansion by the time-honored method of grab-and-keep has become more difficult, far more expensive in manpower and material wealth and is in growing disrepute among a sizeable minority of individuals and social groups, even in the centers of western civilization. It is in notable disfavor among the former colonies and dependencies of the European empires. At the same time, war as a means of achieving social ends has fallen into greater and greater disrepute. War costs, measured in terms of human well-being and welfare had soared to fantastic heights before 1945. The devastation, during that year, of two moderate sized cities, Hiroshima and Nagasaki, was a foretaste of the increasingly bleak chances of human survival with the stockpiling of nuclear weapons far more destructive than the fission bombs used on the two Japanese cities. Under the conditions prevailing before the great revolution, competitive struggle between nations and empires, expanding as a result of victory in war, had ceased to be a practicable means of gaining, holding and increasing wealth and power. If the costs of the international power struggle exceeded the gains, there were no longer victors who won and vanquished who lost. Instead, everybody lost as the entire social structure was wrenched, dislocated, wracked and down-graded. Certainly this seemed to be the plain-as-day lesson of the two general wars and the flurry of minor wars which swept the earth after 1910. Expansion through armed struggle no longer paid its way. It was the obvious lesson stressed by J.A. Hobson and Nicolai Lenin in their respective studies of imperialism (1903 and 1916). It was the theme of Norman Angel's _Great Illusion._ It was summarized by Arnold Toynbee's _War and Civilization._ If the costs of expansion exceeded the income, the outcome of expansion would be dismemberment for the vanquished and bankruptcy for the victors. Indeed, this formula generalises the experience of the survival struggles during the war years which began in 1911. I summarized the experience in _The Twilight of Empire_(1929).
