This letter was written at the time of the first Gulf War in 1991. In the technical letter sent to the Bulletin of the Atomic Scientists, Amory Lovins corrects misstatements about the critical ingredients needed to make active nuclear weapons. Lovins’ calculations reveal previously unexplored implications about Iraq’s nuclear capabilities in the early 1990’s. Lovins criticizes the pattern of thought by the U.S. government as sloppy and misguided. He concludes by calling for rational and enlightened analysis of the nation’s security in a nuclear world.
