"All wars are fought twice, the first time on the battlefield, the second time in memory," writes Pulitzer Prize-winning author Viet Thanh Nguyen. This week on Throughline, we want to pause the news cycle to think about not just how war is experienced or consumed, but how it's remembered. A refugee from the Vietnam War, Nguyen calls himself a scholar of memory — someone who studies how we remember events of the past, both as people and as nations. As the world watches the war in Ukraine — and with the U.S. departure from Afghanistan still fresh — we speak with Nguyen about national memory, selective forgetting, and the refugee stories that might ultimately help us move forward.
