Secretary of State Hillary Clinton cautioned Thursday, June 21, that Iran not be allowed to acquire a nuclear weapon, not only because of its own intentions, but because she believes it would spur a regional arms race, The Hill reported. “Everybody needs to know — most particularly the Iranians — that we are serious that they cannot be allowed to have a nuclear weapon. It’s not only about Iran and about Iran’s intentions, however one tries to discern them. It’s about the arms race that would take place in the region with such unforeseen consequences,” Clinton said in an interview. During the interview Clinton also said that one of the “real successes” of the U.S. diplomatic strategy is that the Chinese and Russians have been a part of a unified negotiating stance towards Iran.
