From an international research project by ICSR @ Kings; the summary ends with:
Fighters’ families are among the most powerful assets in the struggle against IS. Their stories highlight the pain and suffering that aspiring jihadists are causing to their loved ones. Families can be key to stopping their sons and daughters from leaving; encouraging them to defect; and helping them re-integrate once they return. They need to be empowered, not left alone.
