This Revised Anthology is about the future of military operations in the opening decades of the 21st Century. Its purpose is not to predict the future, but to speculate on the conduct of military operations as an instrument of national policy in a world absent massive thermonuclear and conventional superpower confrontation characteristic of the Cold War. Also absent are indirect constraints imposed by that confrontation on virtually all political-military relationships, not solely those between superpower principals. It is likely not possible to predict the future. Its uncertainties increase the number of assumptions that need to be made and taken as fact in order to think ahead. So, all futures investigations are really speculation. Further, looking ahead, it is necessary to accommodate the past. For the present is the leading edge of the past, as well as the line of departure to the future. With us are legacies of the past; we struggle with them daily in problems of the present.
