Hiroshima is a beautiful city with cute trams cruising along its tree-lined streets.

From Nov. 12-14, this City of Peace — as it was proclaimed by the Diet (Japan's parliament) in 1949 — hosted the 11th World Summit of Nobel Peace Laureates. Held during the 65th anniversary year of the U.S. atomic bombings of Hiroshima and Nagasaki, the summit's objective was to help create a world without nuclear weapons, and the holders of 18 Nobel Peace Prizes convened there to draw a roadmap for peace.

Frederik W. de Klerk, the last State President of apartheid-era South Africa (1989-94) recommended that summit attendees identify why people feel they need nuclear weapons.
