Active Measures by Thomas Rid delves into the shadowy world of modern espionage and psychological warfare, offering a compelling narrative that spans over a century of international intrigue. The book illustrates how intelligence agencies around the globe have honed their craft of deception, manipulation, and subversion, often aiming to undermine the essential pillar of liberal democracy: trust in facts. Thomas Rid, an authority on technology and national security, brings his extensive knowledge to light, showing how these deceptive practices have evolved. He provides a profound examination on how entities like the KGB, CIA, and contemporary Russian military intelligence have engaged in 'active measures'—covert operations designed to influence events and public perceptions. Rid sheds light on pivotal historical events while drawing unsettling parallels to our current geopolitical landscape, making it crystal clear that the disinformation campaigns seen today have deep and elaborate roots. In a spellbinding journey through clandestine activities, Rid uncovers some of the most audacious and, at times, almost unbelievable intelligence operations ever conducted. For instance, he recounts how a White Russian scheme inadvertently led to the downfall of a New York police commissioner, and how a KGB-orchestrated anti-Semitic campaign stealthily made its way back across the Berlin Wall. He also reveals less-known operations, such as the CIA's backing of a faux publishing empire managed by a former Wehrmacht U-boat commander, which surprisingly resulted in the production of Germany's premier jazz magazine. This riveting exposé not only brings to light some of history’s most clandestine episodes but also serves as a warning. Active Measures emphasises the importance of vigilance in the face of misinformation and highlights the continuous struggle for factual integrity in the modern world. Rid's meticulous research and engaging storytelling make this a must-read for anyone interested in the intricate dance of global espionage and the silent battles for truth that shape our reality.
