The stories we tell matter. I know this not from watching but from memory. I was just a child, held behind barbed wire in a U.S. internment camp, when an atomic bomb obliterated Hiroshima—killing members of my family. That horror etched itself into my life and forged my belief in the urgency of disarmament. I’ve heard this horror reflected over and over again in the stories of other hibakusha—survivors of these unimaginable attacks.
