"unashamedly bold and far-reaching, proudly concerned with the fundamentals of the discipline, making sense where previously there was very little of it. Ian Clark impresses with thorough knowledge of both the military and the philosophical-ethical dimensions of waging war and the ability to bring them together in a fashion that is both conceptual and immediately practical" -LSE Review of Books
