Ahmadinejad calls his nuclear critics 'traitors'

President Mahmoud Ahmadinejad on Monday called critics of his country's disputed nuclear program "traitors" and vowed to expose their collaboration with Iran's enemies, state media reported. "They are traitors," the official IRNA news agency quoted Ahmadinejad as saying of his critics. "Based on the pledge (I) made with the people, we won't retreat and won't standby. ... We are not revealing them because of some sensitivities, but upon closure of the nuclear issue, we will reveal all these issues," IRNA quoted him as telling a group of students.
