Driving Factors behind Foreign Fighters in Syria and Iraq

Abstract

ABSTRACTWith the rise of the self-proclaimed Islamic State of Iraq and Syria (ISIS), the phenomenon of foreign fighters became a significant security concern. Governments around the world have become preoccupied with the possibility of their citizens leaving for combat zones and then coming back with training and experience. While previously foreign fighters participated in such conflicts as Afghanistan, Bosnia, or Chechnya, today ISIS has attracted record numbers of individuals from various backgrounds. This article examines factors that might be connected with the outflow of foreign fighters to Syria and Iraq. The analysis is based on 190 countries with 103 of them serving as countries of origin for 33,815 foreign fighters. Negative binomial regression is used to evaluate the connection of political, economic, demographic, and social factors to numbers of foreign fighters. The findings indicate that more foreign fighters come from countries with higher Human Development Index levels, unemployment rates, percentages of youth, population size, percentages of Muslim population, emigration levels, Internet penetration, and the presence of Al Qaeda cells. However, the findings further indicate that the effect of these variables is not uniform across majority Muslim and majority non-Muslim countries.
