MESA Group researchers have published a new policy brief in the Russland-Analysen titled "Understanding Russia's Strategic Deterrence: Development, Culture, and Political Significance." Drawing on the analysis of 250 Russian military documents spanning seven decades, the piece traces how Russian military thinking on nuclear deterrence has evolved through seven distinct phases — from initial nuclear acquisition in the 1950s through today's hybrid strategic deterrence model. The brief explains how Russia's strategic culture, shaped by a deep sense of vulnerability alongside an insistence on great power status, has produced a conception of deterrence that is fundamentally different from Western frameworks.
