Do images of war make a difference?

On the PBS Newhour August 18th, host Hari Sreenivasan asks us to consider whether the haunting images of war we have seen over the years make a difference.  Do they spark action and if so, when and how? Unfortunately these questions remain all too relevant as we view this week still another haunting image, this time of a Syrian boy emerging from the rubble left behind in the war which engulfs his country. Hari asks his two guests Anne Barnard, Beirut Bureau Chief for the New York Times and University of Maryland Professor Susan Mueller to consider the impact of this and other images of children we have seen over the years. Professor Mueller is also the author of Compassion Fatigue: How the Media Sell Disease, Famine, War and Death
