"Secret Armies: The New Technique of Nazi Warfare" by John L. Spivak is a historical account written in the late 1930s. This work delves into the covert operations of Nazi agents and their activities in the United States and other parts of the Americas leading up to and during World War II. The book likely highlights the alarming extent of fascist infiltration and propaganda in various nations. The opening of the book serves as a preface wherein Spivak outlines the growing threat posed by Nazi agents across the Western Hemisphere, as they infiltrated nations and spread their ideology. He details how this threat was not just a foreign concern but significantly impacted the security of the United States and its allies. Spivak discusses the systemic organization of these agents, providing examples from Czechoslovakia, where spies were sent in to sabotage and create dissent prior to German invasions, and warns about the more extensive ramifications for democracy and national security if these activities remain unchecked. The author prepares readers for a thorough examination of various plots and the agents behind them in the chapters that follow.
