President Barack Obama will visit Japan on November 12 and 13, 2009.  As this year's recipient of the Nobel Peace Prize and as an advocate for the abolition of nuclear weapons, he has an unprecedented opportunity to continue building momentum towards this goal by visiting Hiroshima and Nagasaki, the only cities on which nuclear weapons have ever been used.  A visit to one, or both, of these cities as well as a speech to the world from Hiroshima would be a bold statement of hope in the months preceeding the Nuclear Nonproliferation Treaty Review Conference (May 2010).
