This is a story unlike any we have previously published. It is much longer than the typical New York Times Magazine feature story; in print, it occupies an entire issue. The product of some 18 months of reporting, it tells the story of the catastrophe that has fractured the Arab world since the invasion of Iraq 13 years ago, leading to the rise of ISIS and the global refugee crisis. The geography of this catastrophe is broad and its causes are many, but its consequences — war and uncertainty throughout the world — are familiar to us all. Scott Anderson’s story gives the reader a visceral sense of how it all unfolded, through the eyes of six characters in Egypt, Libya, Syria, Iraq and Iraqi Kurdistan. Accompanying Anderson’s text are 10 portfolios by the photographer Paolo Pellegrin, drawn from his extensive travels across the region over the last 14 years, as well as a landmark virtual-reality experience that embeds the viewer with the Iraqi fighting forces during the battle to retake Falluja.
