Smith does an admirable job of clarifying and condensing the core concepts from the widely read, and frequently misread "On War". He provides a short biography of Clausewitz and a political / technological backdrop to the environment in which "On War" was written. He explains in depth the main features of Clausewitz's thesis in "On War". Smith further provides an overview of how Clausewitz has been regarded by military thinkers since his death until present day, as well as the potential applications of Clausewitz's theory of war on what Smith refers to as "Hyper-Modern" (Nuclear) and "Anti-Modern" (Asymmetric) warfare. Finally Smith explores the possibility, as some critics claim, that Clausewitz has now, or will soon, outlive his usefulness given the technological, political, and social changes over the past century.
