"All wars are fought twice, the first time on the battlefield, the second time in memory," writes Pulitzer Prize-winning author Viet Thanh Nguyen. 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 war in Ukraine continues and conflicts around the globe displace millions, we speak with Nguyen about national memory, selective forgetting, and the refugee stories that might ultimately help us move forward.
