In Spymaster's Prism: The Fight Against Russian Aggression legendary former spymaster Jack Devine aims to ignite public discourse on our country’s intelligence and counterintelligence posture against Russia, among other adversaries. Spymasters are not spies - their mission is to run and handle spies and spy networks. They exist in virtually all sophisticated intelligence services around the world, including the more high-profile services like the CIA, SVR, SIS, MSS, VAJA and Mossad. Without exception, these spymasters are highly trained and broadly experienced top-level government officials who are at the heart of the intelligence business. They make the life and death decisions. The vast majority of spymasters remain unknown to the world, but there are several legendary figures such as East German spy chief Marcus Wolf and CIA Soviet officer George Kisevalter who rise above the fray. To understand current Russian aggression towards the US, it’s crucial to know the history of it. Spymaster's Prism sheds urgent light on Russian intelligence activities by emphasizing the parallels between tactics used today and those that were employed during the Cold War. Considering this history, and present Russian intelligence activities, Devine also provides hard-edged policy prescriptions for countering Russian hostility going forward.
