From the Preface...

... I have deliberately concentrated on those West-East fault lines that emphasize the singular lethality of Western culture at war in comparison to other traditions that grew up in Asia, Africa, and the Americas. These valid generalizations should not imply that at times there were not real differences among particular European states themselves or that Western and non-Western cultures were either monolithic or always at odds with each other. And while I discuss larger issues of government, religion, and economy, my primary aim is to explain Western military power, not the general nature and evolution of Western civilization at large.

This is not a book, then, written for academic specialists. Instead, I have tried to offer a synthesis of Western society at war for the general reader across some 2,500 years of history that concentrates on general trends, rather than an original work of primary research within a defined historical period. I have used formal scholarly citations in parentheses in the text only for the longer direct quotations—although detailed information concerning factual material is derived from primary sources and secondary books and articles discussed at the conclusion of the book.
