The Hiroshima Statement that emerged this past April from the ministerial meeting of the NPDI (Non-Proliferation and Disarmament Initiative) called on the world’s policymakers to visit Hiroshima and Nagasaki. President Obama and all leaders of nuclear-armed nations, please respond to that call by visiting the A-bombed cities as soon as possible to see what happened with your own eyes. If you do, you will be convinced that nuclear weapons are an absolute evil that must no longer be allowed to exist. Please stop using the inhumane threat of this absolute evil to defend your countries. Rather, apply all your resources to a new security system based on trust and dialogue.
