This book examines the contention that current US-Russia relations have descended into a ‘New Cold War’. It examines four key dimensions of the original Cold War, the structural, the ideological, the psychological, and the technological, and argues that the current US-Russia relationship bears little resemblance to the Cold War. Presently, the international system is transitioning towards multipolarity, with Russia a declining power, while current ideological differences and threat perceptions are neither as rigid nor as bleak as they once were. Ultimately, when the four dimensions of analysis are weighed in unison, this work argues that the claim of a New Cold War is a hyperbolic assessment of US-Russia relations.
