In 1946, the U.S. evacuated the entire population of Bikini Atoll (167 people) and logged the first of 23 atomic weapons explosions that have made what's left of the atoll (part of it was vaporized) a largely uninhabitable radioactive tourist destination [one report says 4-6 "caretakers" live there]. Most of the 167 original residents have died, but their descendants number more than 4,000. A 1975 federal lawsuit (seeking roughly $750 million in compensation promised but not paid by the U.S.) was denied review by the U.S. Supreme Court in April 2010, but the effort to make the U.S. provide just compensation continues.
