Dirty little secrets of the twentieth century

Dirty Little Secrets of the Twentieth Century was authored by James F. Dunnigan, a noted military analyst and wargame designer, and published by William Morrow in 1999. The book emerged from Dunnigan's extensive background in systems analysis and military history, reflecting a broader movement in late-twentieth-century non-fiction that sought to demystify geopolitical events and conflicts for a general audience. It is organized as a thematic collection of concise, information-dense entries that challenge common historical narratives by focusing on the often-overlooked logistics, blunders, and structural realities behind major global events.

The design of the work prioritizes accessibility and quick reference, utilizing a format that echoes the author's professional experience in simplifying complex tactical data. By stripping away the romanticized veneer of historical figures and political movements, Dunnigan aimed to provide readers with a grounded, often cynical look at the mechanics of the century. The book was well-received by readers interested in military history and political science, praised for its willingness to prioritize empirical observation and strategic assessment over traditional moralizing or consensus history.
