"That Clausewitz lives, and will live, is equally shown in such cases as the former Yugoslavia, where Nato has simply frozen a war which will certainly break out again if and when the intervention forces leave; or Israel–Palestine, where the political relations between Jew and Arab reflect the military outcome of past wars, where the conflict of interest is essentially irreconcilable, and where therefore policy and violence will continue to go hand in hand. What may therefore be safely predicted is that over the next 170 years the world will continue to be an arena of complex rivalries and direct collisions of interest rather than a "world order" or a "world community", and that human groups engaged in such rivalries will from time to time resort to force as an instrument of their politics. What weapons will be then available, and what tactics will consequently be employed, only a fool would pretend to guess. It will be remarked that so far I have not mentioned the United Nations Organisation, that expensive figment of liberal wishful thinking. I have done so now."
