The Center for Security Studies (CSS) at ETH Zürich released a detailed November 2023 analytical report by Lennart Maschmeyer examining the enduring concept of Hybrid War. The paper outlines the broad, often vague usage of the term which encompasses gray zone tactics including cyber operations, disinformation, sabotage, and covert military actions. It critiques the optimistic expectation of a technological revolution enabling unprecedented strategic effects through information technologies, noting that major cases such as Russia's 2014 annexation of Crimea had minimal cyber or social media involvement, relying instead on traditional proxy subversion. Subsequent Russian cyber campaigns against Ukraine and Estonia indicated limited disruptive impact and frequently strengthened the targeted nations' resilience by catalyzing defensive initiatives like NATO's cyber defense center. The paper also scrutinizes the 2016 US presidential election interference allegations, acknowledging Russian efforts but citing research that found no measurable effect on voting outcomes. It highlights that Russia's hybrid attempts failed to prevent a full-scale invasion in 2022 as strategic goals remained unmet. The report categorizes Hybrid War's mechanisms into influence operations aimed at opinion manipulation, sabotage to degrade infrastructure, subversion including cyber as a new element, and covert armed tactics exemplified by unmarked forces. It stresses the urgency for policymakers to conduct systematic, evidence-based assessments to clarify the real threat posed by these hybrid means and to tailor defensive strategies effectively. The document notes ongoing significant resource allocation by Western states to counter hybrid threats, including NATO's strategic prioritization since 2015 and the EU's first hybrid threat mission deployed to Moldova in 2023. It also references Russia's justification of a 70% military budget increase citing threats from Western hybrid warfare, and China's elevation of cognitive warfare in its doctrine. Overall, the analysis encourages refinement and differentiation of hybrid threat instruments to better understand their operational conditions and limitations.
