HIROSHIMA, Japan — President Obama laid a wreath at the Hiroshima Peace Memorial on Friday, telling an audience that included survivors of America’s atomic bombing in 1945 that technology as devastating as nuclear arms demands a “moral revolution.”
Thousands of Japanese lined the route of the presidential motorcade to the memorial in the hopes of glimpsing Mr. Obama, the first sitting American president to visit the most potent symbol of the dawning of the nuclear age. Many watched the ceremony on their cellphones.
“Seventy-one years ago, on a bright cloudless morning, death fell from the sky and the world was changed,” Mr. Obama said in opening his speech at the memorial.
“Technological progress without an equivalent progress in human institutions can doom us,” Mr. Obama said, adding that such technology “requires a moral revolution as well.”
