The Marshall Islands is suing the United States and eight other countries, accusing them of failing to meet commitments for nuclear disarmament. In an unprecedented legal action brought before the International Court of Justice at The Hague, the tiny Pacific island nation accuses the nine countries of “flagrant violations” of international law, saying they are upgrading their nuclear arsenals instead of working to reduce them. The Marshall Islands chain, which includes Bikini Atoll, was the subject of 67 nuclear tests in the 1940s and 1950s, which have left lasting health and environmental impacts.
