Japan's government is rushing to try to restart two nuclear reactors idled after the 3/11 disaster. Experts believe they're motivated by a fear that surviving a total shutdown will make it hard to convince the public that atomic energy is vital. "They want to avoid setting a precedent of the country operating without nuclear power because it will create a huge barrier in terms of restarts," said Jeffrey Kingston of Temple University, Japan Campus. "People will question why we need it," he said.
