This article critically examines the effects of the Syrian crisis on ‘foreign fighters’ by placing a special emphasis on problems emanating from the prolongation of the crisis. In doing this, the article discusses various issues such as non-intervention, the principle of the Responsibility to Protect (R2P) and the ‘Paris Commune Effect’ of the activities of the Islamic State of Iraq and Sham (ISIS) in Syria and Iraq. In a nutshell, this article argues that efforts regarding the foreign fighters issues must be supported by an actual and concrete intent to resolve the Syrian crisis. The approach of Western states, since the civil war in Syria, has proved to be counterproductive as it has caused the radicalization of more individuals living in those places.
