"Nuclear weapons are not a necessary evil but an absolute evil, and can never coexist with humanity," Mayor Shiro Suzuki said in a speech broadcast by Japanese public television channel NHK. Japanese Prime Minister Sanae Takaichi said her government defended the three principles without clarifying whether the country would continue to respect them in the future. She said the government would defend realistic and practical measures to achieve a world free of nuclear weapons. On August 9, 1945, the United States dropped a plutonium-fueled atomic bomb nicknamed Fat Man on Nagasaki, killing about 40,000 people instantly. Three days earlier, the US had dropped a similar bomb called Little Boy on Hiroshima killing an estimated 80,000 people.
