The top diplomat of the Marshall Islands, a Pacific nation once used in U.S. nuclear bomb tests in the postwar years, called for people to look back at the dangers of nuclear weapons, as Japan marked the 75th anniversary of the atomic bombing of Hiroshima and Nagasaki last month.

Foreign and Trade Minister Casten Nemra said in a written interview that survivors of radiation exposure, including those who live in his Pacific island nation, have a unique perspective that must be preserved by society as their number dwindles with time.

"We have to ensure that these experiences are recorded and also shared directly with our youngest and future generations," Nemra said, adding that no country should have to suffer the effects of exposure to nuclear fallout.
