For me, my home is a peaceful place where I can rest, and it gives me back energy.

If Mr. Obama could walk across the Peace Bridge in Hiroshima - whose balustrades were designed by the Japanese-American sculptor Isamu Noguchi as a reminder both of his ties to East and West and of what humans do to one another out of hatred - it would be both a real and a symbolic step toward creating a world that knows no fear of nuclear threat.
