This article examines the critical strategic question of whether Russia possesses the capability to destroy the United States with a nuclear first strike while successfully precluding a devastating retaliatory response. Based on analysis of open-source intelligence, strategic force postures, official statements, and expert commentary, this study deconstructs the technical, operational, and doctrinal dimensions of this question. Particular attention is devoted to the structure of Russian strategic forces, the capabilities of the US nuclear triad and early warning systems, the role of automatic retaliatory systems like "Perimeter," and the fundamental strategic stability paradigm that has defined US-Russian relations for decades.
