The indications, then and since, that the development of nuclear weapons did not bode well for human survival, were clear enough. The two small atomic bombs dropped on the cities of Hiroshima and Nagasaki killed between 110,000 and 210,000 people and wounded many others, almost all of them civilians. In subsequent years, hundreds of thousands more people around the world lost their lives thanks to the radioactive fallout from nuclear weapons testing, while substantial numbers also died from the mining of uranium for the building of nuclear weapons.
