In the 1940s and ’50s, the U.S. conducted 67 nuclear weapon tests on the Marshall Islands. The explosions and nuclear fallout wreaked unspeakable devastation on the islanders. @mark.harmony, a Marshallese band, sings about the intergenerational trauma and displacement caused by these nuclear tests. Recently, Russia pulled out of the nuclear test ban treaty, and China is reportedly upgrading test sites. Some fear that testing could soon resume. #nuclearweapons #nuclearwar #acappella #nytopinion

National security writer Bill Hennigan has spent many years ringing the alarm about the world’s new nuclear era — the subject of At the Brink, a new series from @nytopinion — and the crisis on the horizon. For anyone whose interest was piqued by the origin story of nuclear weapons in “Oppenheimer,” Bill, who happens to be a movie buff, recommends three essential films that illuminate our new nuclear era. We make tons of audio essays like this every week, from voices across the Opinion section. You can hear them all right now in the New York Times audio app, available for Times subscribers in the Apple App Store. | 🎨 Akshita Chandra/The New York Times; 📷 Universal Pictures/Alamy #oppenheimer #nuclearweapons #filmtok #nytopinion

We are witnessing the dawn of a new nuclear era and, with it, a burgeoning arms race. Yet most of the world has barely registered the current threat. Check out our new project, At the Brink. #nuclearweapons #nuclearwar #nytopinion
