In 1945, the horrors unleashed in Hiroshima and Nagasaki were largely hidden from the outside world. Eighty years later, thanks to the testimonies shared by those who survived the atomic bombings of my country, we have a window into the truth of what happened on those dark August days when weapons of previously unimaginable power destroyed our cities. We also know what happened over the torturous months and years that followed, as those who weren't immediately burned alive succumbed to radiation poisoning and cancer. Nuclear bombing survivors have helped ... fuel public demand for post-Cold War arms-control treaties that resulted in significant stockpile reductions in the United States and Russia. They helped persuade nuclear-armed countries to stop explosive weapons tests that caused grave harm to the environment and to the servicemembers and civilians involved. They worked to establish the "nuclear taboo" that has spared the use of nuclear weapons in warfare for eight decades. They delivered millions of petition signatures to the United Nations that helped ... reduce nuclear risks. Again and again, they have proved that progress is possible, and for their decades of work to ensure that ... no country ever again face the unthinkable, the survivors in 2024 were awarded the Nobel Peace Prize. Demanding a nuclear-free world isn't naive. True naivete is believing that weapons designed to annihilate cities will keep us safe.
