Hybrid threat modeling

9 May 2025

Hybrid threats pose a complex and evolving challenge to Western governments. These threats span military and civilian domains, blending conventional and unconventional tactics, remaining below the threshold of armed conflict. Their ambiguity and unpredictability make them difficult to detect and counter. Our most recent research by Maarten Vonk and Tim Sweijs uses game-theoretic modelling to evaluate the effectiveness of various counter-measures—ranging from enhancing societal resilience and denying adversaries the means to act, to dissuasion through the threat of punishment.

The Socio-Political Instability Observer: January 2025

7 May 2025

The fifth edition of the ‘Observer’, analysing the results of the HCSS Socio-Political Instability Survey, continues to monitor high levels of instability in Western Asia and Eastern Europe. Despite a Gaza ceasefire, tensions between Israel and Iran and the fallout from Syria’s regime collapse persist. Ukraine now tops the list of high-risk countries, likely due to war-related uncertainty. Notably, the U.S. has surged as the most influential country in global instability, rising from 15% to 60%, reflecting concerns over Trump’s second-term policies. Economic factors have overtaken military ones as the main drivers of instability, amid growing fears of trade wars.
