The Bush administration is pressing U.N. inspectors to broaden their search for possible secret nuclear facilities in Syria, hinting that Damascus's nuclear program might be bigger than the single alleged reactor destroyed by Israeli warplanes last year.
Do not assume that Al Kibar exhausted our knowledge of Syrian efforts with regard to nuclear weapons," Hayden said. "I am very comfortable -- certainly with Al Kibar and what was there, and what the intent was. It was the highest confidence level. And nothing since the attack last September has changed our mind.
The absence of a clear fuel source for the reactor -- as well as a fuel-reprocessing facility for extracting plutonium -- has baffled experts who have studied the Syrian project. "It's like having a car but not enough gas to run it," said David Albright, a former U.N. nuclear inspector in Iraq and the president of the Institute for Science and International Security.
