Australia’s Prime Minister Kevin Rudd’s entry in the visitors’ book at the Hiroshima Peace Memorial Museum last month may not sound so astonishing or dramatic. His words — “Let the world resolve afresh, from the ashes of this city, to work together for the common mission of peace for this Asia-Pacific century, and for a world where nuclear weapons are no more” — sound like many other entries written in the visitors’ book after people learned the truth of the effect of the use of nuclear weapons against humanity.
