An Iraqi man who refuses to give up on the decimated city of Baghdad opened an art gallery in the northern part of town last year, and has doggedly kept it open even as life continues to crumble all around him. “He has kept it alive with a relentless rotation of exhibits, lectures, poetry readings and film screenings. There is urgency to this schedule. Mr. Nassar believes that culture can provide a pathway out of the hate and fear overwhelming Iraq, and he is trying to marshal like-minded Iraqis to join his movement.”
