With at least 6,800 European nationals fighting in Syria and Iraq, and estimates suggesting that approximately a quarter – nearly 2,000 – have already returned, the risk is not insignificant. Monitoring these returnees has added significant strain to European intelligence and security services. Closer examination of the available data shows a variance in the number of returnees per country. A (rough) distinction can be made between Northern and Southern European countries (see figure). While countries such as Italy (10.5%), France (14.2%), and Spain (14.7%) are facing relatively low percentages of returnees, countries such as Denmark (49.6%), the United Kingdom (50%), and Finland (53.8%) have a significantly higher share of jihadi foreign fighters returning. Where does this variance stem from?
