Survivors of the world’s first atomic bombing gathered in diminished numbers near an iconic, blasted dome Thursday to mark the attack’s 75th anniversary, many of them urging the world, and their own government, to do more to ban nuclear weapons.Hiroshima and Nagasaki: 75 Years Later 2020. An upsurge of coronavirus cases in Japan meant a much smaller than normal turnout, but the bombing survivors’ message was more urgent than ever. As their numbers dwindle – their average age is about 83 – many nations have bolstered or maintained their nuclear arsenals, and their own government refuses to sign a nuclear weapons ban treaty. Amid cries of Japanese government hypocrisy, survivors, their relatives, and officials marked the 8:15 a.m. blast anniversary with a minute of silence. The United States dropped the world’s first atomic bomb on Hiroshima on Aug. 6, 1945, destroying the city and killing 140,000 people. It dropped a second bomb three days later on Nagasaki, killing another 70,000. Japan surrendered Aug. 15, ending World War II and its nearly half-century of aggression in Asia. But the decades since have seen the weapons stockpiling of the Cold War and a nuclear standoff among nations that continues to this day. Monday Sunrise Briefing: Is a global tax a path to fairness? Amid the solemn remembrances at Hiroshima’s peace park, Prime Minister Shinzo Abe was confronted Thursday by six members of survivors’ groups over the treaty. “Could you please respond to our request to sign the Nuclear Weapons Prohibition Treaty?” Tomoyuki Mimaki, a member of a major survivors’ group, Hidankyo, implored Mr. Abe. “The milestone 75th anniversary of the atomic bombing is a chance [to change course].” Mr. Abe insisted on Japan’s policy not to sign the treaty, vaguely citing a “different approach,” though he added that the government shares the goal of eliminating nuclear weapons. “Abe’s actions don’t seem to match his words,” said Manabu Iwasa, who came to the park to pray for his father, a bombing survivor who died in March. “Japan apparently sides with the United States, but it should make more efforts to eliminate nuclear weapons. It’s frustrating, but there is not much we individuals can do.”
