A new research piece from the Combating Terrorism Center (CTC) takes a fresh look at the global picture of foreign terrorist fighters (FTFs) and offers a nuanced assessment: the threat hasn’t disappeared, but it also hasn’t surged. Instead, researchers describe it as being “in stasis”—persistent, adaptive, and still capable of shaping extremist networks worldwide.
The study traces the long arc of foreign fighter activity, linking today’s Islamic State–aligned operatives to earlier generations connected to al-Qa`ida and the Arab Afghans. The throughline is clear: foreign fighters have always played a role in exporting violence, moving between conflict zones, and carrying new tactics, techniques, and procedures wherever they go.
According to the analysis, those patterns continue. FTFs remain involved in external attack plotting against Western targets and continue to act as conduits between Islamic State affiliates and supporters abroad. What’s changed is how they communicate and influence. Today’s networks use encrypted messaging, generative AI tools, and cryptocurrencies to recruit, coordinate, and move resources with greater speed and anonymity.
The report titled: Foreign Terrorist Fighters: A Threat in Stasis, stresses that none of these developments signal an immediate escalation. In fact, many governments have spent the past decade strengthening relevant laws, sharpening intelligence-sharing, and tightening law enforcement cooperation specifically aimed at tracking and disrupting foreign fighter travel and activity. Those measures, the authors argue, have helped keep the threat from expanding.
But the study also cautions against complacency. The stability of the threat hinges on continued investment—both in monitoring foreign fighter flows and in maintaining the partnerships that make it possible to detect them early.
