HIROSHIMA, Japan — Japan marked the 70th anniversary of the atomic bombing of Hiroshima on Thursday, with Mayor Kazumi Matsui renewing calls for U.S. President Barack Obama and other world leaders to step up efforts toward making a nuclear-weapons-free world.
Tens of thousands of people stood for a minute of silence at 8:15 a.m. at a ceremony in Hiroshima’s peace park near the epicenter of the 1945 attack, marking the moment of the blast. Then dozens of doves were released as a symbol of peace.
The U.S. bomb, “Little Boy,” the first nuclear weapon used in war, killed 140,000 people. A second bomb, “Fat Man,” dropped over Nagasaki three days later, killed another 70,000, prompting Japan’s surrender in World War II.
We must establish a broad national security framework that does not rely on use of force but is based on trust.
