On Saturday, twin bells tolled in Nagasaki as the city commemorated 80 years since the U.S. dropped the atomic bomb. The attack on August 9, 1945, killed 74,000 people, three days after the atomic bombing in Hiroshima, which killed 140,000 people. At the ceremony, the mayor of Nagasaki called for an end to all wars, saying, “If we continue on this trajectory, we will end up thrusting ourselves into a nuclear war.”
