Today marks 65 years since the atomic bomb was dropped on the city of Hiroshima on August 6, 1945. The aftermath of the nuclear attacks on Hiroshima and Nagasaki were horrific, and the lives lost can only be estimated but it numbers in the hundred thousands. The attacks over sixty years were the first and only instances thusfar in which nuclear weapons have been used offensively in warfare.

As the granddaughter of a Hiroshima survivor (hibakusha), I’ve heard firsthand stories from my grandmother about the atrocity that befell the city that day. Her father was killed, along with many of her family members and friends. The atomic bomb not only took away countless lives, but it continues to have long-lasting effects… some genetic, that are passed on through the generations. Even I myself am not completely free from risk of unforeseen radiation effects, as the blood of a survivor runs through my veins.

Still, the constant message that is central at the Hiroshima Peace Park and at its yearly memorial services on August 6 is not that of bitterness, but of the city’s unending hope for world peace. Hiroshima is an important reminder that the world should never have to experience such a nuclear nightmare ever again.
