This news on Iran: the Washington Post is reporting that a group of U.S. government experts and other international scientists have determined that traces of bomb-grade uranium found two years ago in Iran came from contaminated Pakistani equipment and are not evidence of a clandestine nuclear weapons program. One senior official said, “The biggest smoking gun that everyone was waving is now eliminated with these conclusions.” The Bush administration had pointed to the material as evidence that Iran was making bomb-grade ingredients.
