Before the next nuclear crisis, listen to those who lived through the last one

By Renata Hessmann Dalaqua, Rebecca Davis Gibbons | Opinion

In August 1945, the United States used nuclear bombs on the Japanese cities of Hiroshima and Nagasaki. It was the first and remains the last time that nuclear weapons have been used in war. The story of how those bombs were made, the decision to use them, and the effects on Japan and its people have been central to conversations around nuclear weapons ever since. To mark 81 years since that August, the Bulletin is bringing together three storytellers who have engaged with that history in diverse ways to talk about what happened, what society remembers (and what it doesn’t), and why telling these stories is still crucial more than eight decades into the nuclear era. Join us on August 18 at 10:15 a.m. CT for this Bulletin virtual event.
