Epistemological revision of clausewitz's concept of “Absolute war” in the context of hybrid action in the grey zone: a theoretical framework for contemporary operationalisation

Carl von Clausewitz's distinction between absolute war (the warlike element taken to its ultimate expression, in which the spirit of fighting is unencumbered by any external constraint) and real war (war as actually fought, conditioned by friction, political restraint, and the trinity of people, army, and government) has structured western strategic theory for nearly two centuries. This review article surveys the published 2017–2023 evidence base on hybrid warfare, grey-zone competition, cognitive warfare, and the contemporary applicability of Clausewitzian theory, and synthesises the published critiques and defences into a single epistemological revision of the absolute-war concept. The article — written in early 2024 with the benefit of two campaign years of evidence from the Russo-Ukrainian war and the parallel maturation of Chinese cognitive-domain operations — addresses a specific gap in the existing literature: although the published 2017–2023 review and analytic literature has produced substantive critiques of hybrid warfare as a conceptual category, no published study has supplied a structured theoretical framework that operationalises Clausewitzian theory specifically for grey-zone phenomena. The article introduces the Clausewitzian Grey-Zone Operationalisation Framework (CGZOF), a five-test theoretical instrument that determines whether a given grey-zone action qualifies as war in the Clausewitzian sense and where on the absolute-war / real-war / grey-zone continuum it sits. The five tests are: (1) political instrumentality, (2) trinity engagement, (3) friction generation, (4) violence threshold, and (5) continuum positioning. The article applies the CGZOF to the principal grey-zone-action cases documented in the 2017–2023 literature — the Russian operations in Ukraine (2014–2022 sub-period), the Russian invasion of Ukraine (2022–2023), the Chinese cognitive-domain operations in the Indo-Pacific, and the Russian information-operations campaign — and concludes that Clausewitzian theory, with the absolute-war concept properly understood as a regulative ideal rather than as a phenomenological description, retains substantial analytic adequacy for the contemporary strategic environment.
