No, I don't think so. The Israelis, for instance, have never tested a weapon. Well, there's some dispute about whether they and the South Africans tested a weapon, but it doesn't appear the Israelis have tested a weapon. And the weapons design the Iranians seem to be going for is 60-year old technology. When the United States built nuclear weapons during World War II, we developed two designs. One was a design that we weren't sure would work, so we tested it at the Trinity site. But we still weren't so sure it would work well; therefore, what we dropped on Hiroshima was a bomb that had never been tested. And that is the type of bomb Iran is building, so it is a pretty straightforward technical thing. Getting it to fit on a missile is harder.
