US Secretary of State Condoleezza Rice raised fresh doubts Thursday about the nature of Iran's nuclear program, saying if the clerical state really wanted only an avenue to peaceful atomic energy it could quickly have it. Instead, Iran is stonewalling on an attractive deal to trade away only the part of the program that could result in a nuclear weapon, Rice said ahead of a gathering of the UN nations that have presented a carrot-or-stick package to Iran. "I continue to suspect this is not at all about a civil nuclear program," Rice told reporters traveling with her. Iran's insistence that it be able to enrich uranium on its terms seems at cross-purposes with that goal, Rice said. "One has to wonder what is going on here."
