Security challenges in the grey zone : Hybrid threats and hybrid warfare

The international security environment has in recent years evolved into a volatile and increasingly grey zone of war and peace. Security challenges arising from hybrid threats and hybrid warfare, henceforth HT&HW, are today high on security agendas across the globe. However, despite the attention, and a growing body of studies on specific issues, there is an imminent need for research bringing attention to how these challenges can be addressed in order to develop a comprehensive approach towards identifying, analysing and countering HT&HW. This volume supports the development of such an approach by bringing together practitioners and scholarly perspectives on HT&HW, by covering the threats themselves as well as the tools and means to counter them together with a number of real-world case studies. Over time the grey zone between peace and war has grown considerably, underscoring the necessity of understanding hybrid warfare and related threats. Russia’s actions in Ukraine have manifested this paradigm, being a good example of the problem in thinking about war and peace as binary categories. How does a country or group of countries deal with threats and aggression in this grey area, such as ‘little green men’ that appear in uniform but without national denomination and refuse to tell where they come from, election-influenced operations or cyberattacks, to mention but a few possible actions. By uniting the knowledge of both practitioners and scholars, the volume aims to identify the existing tools for countering HT&HW, as well as experiences from a wide set of empirical contexts. Mirroring this, the project is a cross-sector collaboration between the Department of Military Studies and the Center for Asymmetric Threat Studies (CATS) at the Swedish Defence University. The former represents an academic environment where research and teaching are intertwined in a range of subjects including War Studies, Military Technology and Military History. The latter is a national centre within the Swedish Defence University tasked with developing and disseminating knowledge about asymmetric threats within the context of societal security and resilience. This volume focuses on the challenge posed by HT&HW to Western democracies, and their ability to address it. Western democracies are not only the type of states most frequently targeted by hybrid measures, but also the most vulnerable. By virtue of being open, pluralistic and liberal societies with freedom of the press and rule of law, Western democracies display both inherent weaknesses that can be targeted and inherent constraints – in particular through the rule of law and basic freedoms – that limit the scope for defensive actions. These vulnerabilities are increasingly recognized by Western governments, which have developed a range of entities to address them, although coordination in many instances remains weak. The later sections outline the growing significance of HT&HW on the security agendas of Western democracies and the challenges they imply, as well as the entities these states have established in response. Although neither list is complete, they provide an overview of the current situation. The final sections provide an outline of the volume’s structure and a summary of each chapter
