Hiroshima and the Future

The Atomic Bomb dome, an historical monument (one of at least 60) in the now thriving city of Hiroshima, preserved in the condition it was after the explosion of the first atomic bomb used on a human population in wartime on August 6, 1945.  The Guardian has this nuanced article about Hiroshima today.  Meanwhile, the effort to ban nuclear weapons worldwide continues in the UN.  It seems about as hopeless as banning slavery once did.
