Now we remember. The Peace Memorial Park (Heiwa Kinen Koen) is there. The Cenotaph, shaped like an ancient tomb, holds the names of the dead. The prayer, the hope, in Japanese reads "Repose ye in peace, for the error shall not be repeated." The skeleton of the Atomic Bomb Dome (Genbaku Domu) turns green with age against a blue sky. Until all nuclear arms are banned and destroyed, the Eternal Flame yet flickers. Pretty young girls stop to have their pictures taken. Families row in brightly colored boats on a light-hearted Sunday picnic. A lost balloon floats at treetop level; a child cries. An international law should be passed – the first official act of any head of state must be a solitary pilgrimage to Hiroshima.
