What about those trying to build them?

(Reuters) – Iranian President Mahmoud Ahmadinejad said on Thursday the age of nuclear deterrence was long gone and any country still stockpiling nuclear weapons was “mentally retarded”.

He again denied Iran was trying to develop nuclear weapons, a day after the re-election victory of U.S. President Barack Obama, for whom Tehran’s disputed nuclear program will be one of the thornier foreign policy issues of his second term.

“The period and era of using nuclear weapons is over … Nuclear bombs are not anymore helpful and those who are stockpiling nuclear weapons, politically they are backward, and they are mentally retarded,” Ahmadinejad told reporters at a forum to promote democracy on the Indonesian island of Bali.

“The Iranian nation is not seeking an atomic bomb, nor do they need to build an atomic bomb … For defending ourselves we do not need a nuclear weapon,” said Ahmadinejad.
