Today, on the 67th anniversary of the bombings of Hiroshima and Nagasaki, we need to call an end to the nuclear experiment. At 8:15 a.m. on Aug. 6, 1945, the United States dropped an atomic bomb on Hiroshima, killing around 140,000 people. The death toll included men, women and children who died instantaneously, and thousands who died within months from the lingering radiation sickness. The U.S. attack on Nagasaki three days later took the lives of 75,000 more.
