On April 24, US officials briefed lawmakers on Syria's covert nuclear reactor. They explained their "high confidence" that what was destroyed last September in Syria was in fact a nuclear reactor for the production of plutonium, and that it was built with the long-term and sustained assistance of North Korea. In contrast to this certainty, a central aspect of their estimate regarding Syria's nuclear plans adopted a vaguer tone: when asked whether the material to be produced by the reactor would be used in a nuclear weapons program, the Intelligence officials accorded this only a "low confidence" level.
