The contributions gathered in this fascinating collection, in which scholars from a diverse range of disciplines share their perspectives on Russian covert activities known as Russian active measures, help readers observe the profound influence of Russian covert action on foreign states policies, cultures, peoples mentality, and social institutions, past and present. Disinformation, forgeries, major show trials, cooptation of Western academia, memory, and cyber wars, and changes in national and regional security doctrines of states targeted by Russia constitute an incomplete list of topics discussed in this volume. Most importantly, through a nexus of perspectives and through the prism of new documents discovered in the former KGB archives, the texts highlight the enormous scale and the legacies of Soviet/Russian covert action. Because of Russias annexation of Crimea in 2014 and its on-going war in Ukraines Donbas, Ukraine lately gained international recognition as the epicenter of Russian disinformation campaigns, invigorating popular and scholarly interest in conventional and non-conventional warfare. The studies included in this collection illuminate the objectives and implications of Russias attempts to ideologically subvert Ukraine as well as other nations. Examining them through historical lenses reveals a cultural clash between Russia and the West in general.
