US Senator Hillary Clinton called for United Nations sanctions against Iran as it resumes its nuclear program and faulted the Bush administration for "downplaying" the threat. In an address Wednesday evening at Princeton University, a Democrat representing New York state, said it was a mistake for the United States to have Britain, France and Germany head up nuclear talks with Iran over the past 2 1/2 years. Last week, Iran resumed nuclear research in a move Tehran claims is for energy, not weapons. "I believe that we lost critical time in dealing with Iran because the White House chose to downplay the threats and chose to outsource the negotiations," Clinton said. While Clinton was critical of the administration, she never mentioned the president by name and did not engage in the same sort of sharp rhetorical attack against him or other Republicans as she did earlier this week.
