Ali and Suzanne are joined by Renad Mansour and Zmkan Ali of Chatham House to discuss their new report on cross-border conflict. Why is Sinjar, stuck between Iraq and Syria, enmired in other ongoing conflicts?  And can anything be done to improve the situation in Sinjar while those conflicts are unresolved? Renad and Zmkan argue that unless the non-state armed groups active in Sinjar are involved in negotiations about the future of Sinjar, then there will be no lasting resolution.
