Congratulations to Nihon Hidankyo, a group of survivors of the atomic bombs dropped on Hiroshima and Nagasaki, for winning the Nobel Peace Prize. At a time when the threat of nuclear weapons is growing – and the taboo against threatening their use is weakening – Nihon Hidankyo’s work reminds us that these weapons have a terrible human cost, and that the pursuit of a world without nuclear weapons is an essential part of making sure we leave our children a safer, more secure world. Nihon Hidankyo built a powerful movement out of personal tragedy and insists upon our common humanity.
