This book examines the evolution and practice of interrogation techniques across three major 20th and 21st-century conflicts. It analyzes the historical context, methodologies, and ethical considerations of interrogation in World War II, the Vietnam War, and the Iraq War. The author, John A. Wahlquist, draws upon historical records and analyses to present a comparative study of these distinct periods. The work aims to understand how interrogation practices have changed and what common threads persist through these conflicts.

The book is likely to be of interest to scholars and students of military history and international relations. Its comparative approach across distinct historical periods suggests a focus on the evolution of interrogation as a tool of warfare and intelligence. The analysis of World War II, Vietnam, and Iraq provides a broad scope for understanding shifts in methodology and ethical considerations. The work appears to offer a structured examination of a critical aspect of modern conflict.
