"We stand here, in the middle of this city, and force ourselves to imagine the moment the bomb fell. We force ourselves to feel the dread of children confused by what they see. We listen to a silent cry. We remember all the innocents killed across the arc of that terrible war, and the wars that came before, and the wars that would follow. Mere words cannot give voice to such suffering, but we have a shared responsibility to look directly into the eye of history and ask what we must do differently to curb such suffering again. Someday the voices of the hibakusha will no longer be with us to bear witness. But the memory of the morning of August 6th, 1945 must never fade. That memory allows us to fight complacency. It fuels our moral imagination. It allows us to change. And since that fateful day, we have made choices that give us hope. The United States and Japan forged not only an alliance, but a friendship that has won far more for our people than we could ever claim through war. The nations of Europe built a Union that replaced battlefields with bonds of commerce and democracy. Oppressed peoples and nations won liberation. An international community established institutions and treaties that worked to avoid war and aspire to restrict and roll back, and ultimately eliminate the existence of nuclear weapons."
