As the changes wrought by the Information Revolution and the rise of great power competition play out in global affairs, theorists are revisiting accepted wisdom about deterrence as an explanation for ongoing events and as a guide for strategy. In this theoretically sophisticated and empirically rich foray into today’s strategic milieu, Dima Adamsky explains how scholars have come to reassess the interaction between strategic culture, dominant conceptions of deterrence, and various deterrent strategies. The concept of “tailored deterrence,” whereby deterrent policies are matched to the cultural idiosyncrasies of the opponent, and “cross-domain” deterrence, whereby scholars ponder the potential interaction among traditional (air, sea, land) and emergent (space, cyberspace, artificial intelligence) warfare domains, are some recent Western examples of the effort to adapt deterrence theory and strategy to today’s international setting. Integrated deterrence, a concept introduced in the 2022 US National Defense Strategy, is another effort to synchronize activities across warfare domains in a deliberate whole-of-government, whole-of-alliance approach to deterrence.
