Discussions of technology and the future of world politics all too often degenerate into meaningless utopian assertions about creating the conditions for permanent global peace. Worthy as this goal is, there is no sound basis for believing that it will be attained in this century for the quite simple reason that this would require a revolution in human nature that is likely not forthcoming. The impact of technology on global politics is, however, an issue of great importance because it is probable that in the near future the grammar of international politics and war will change dramatically even if its essential character does not. Polities will continue to compete, and will threaten, and sometimes use, organized violence against each other; however, how they make war will change radically.
