Nagasaki is marking the U.S. atomic attack on the southern Japanese city 80 years ago and survivors of the attack are working to make their hometown the last place on earth hit by the bomb. Despite their pain from wounds, discrimination and illnesses from radiation, survivors have publicly committed to a shared goal of abolishing nuclear weapons. The atomic bomb dropped by the United States on Nagasaki on Aug. 9, 1945, killed some 70,000 people, three days after the bombing of Hiroshima killed 140,000.
