These programs are aimed to detect and intervene against violent extremism before an individual becomes a foreign terrorist fighter (FTF). Radicalization to violent extremism is a complex process that must be addressed through comprehensive means. While radicalization to violent extremism is a wider phenomenon having the potential to accelerate the radicalization process of FTFs, not all individuals who radicalize to violent extremism become FTFs. In the same vein, while some FTFs are radicalized to violent extremism prior to departure from their countries, others become radicalized to violent extremism while fighting or upon their return.
