My friend Karim Ben Khelifa, an award-winning photographic journalist who I met over a decade ago, has produced an extraordinary film (“The Enemy”) on his experience as a photographer of war and violence in Iraq, Afghanistan, Palestine, the Democratic Republic of Congo and El Salvador, as well as 80 countries overall. On Youtube there is a talk he gave in 2019 about his work. including a number of his photographs. His amazing skill as a photographer is matched by his passion to show the reality of treating other human beings as enemies.

Karim has also taken photographs in Yemen over a decade ago. Some of these are archived on the New York Times blog. One of my favorites is the image of the mammoth mosque built in Sanaa by the late President Ali Abdullah Salih.
