Author: Syrian conflict ‘was existential’ from the start

Rania Abouzeid has been one of the closest chroniclers of the Syrian conflict, witnessing the first days of peaceful protests, the government's brutal crackdown, the rise of the Islamic State, the intervention of the Russians. Abouzeid joins William Brangham to discuss her book, "No Turning Back: Life, Loss and Hope in Wartime Syria," which tells the story of those who have fought and endured.
