Iranian President Mahmoud Ahmadinejad stood fast Thursday in maintaining Iran's right to nuclear technology on the day of a UN deadline to roll back on its nuclear program or face sanctions. "The Iranian nation will not accept for one moment any bullying, invasion and violation of its rights," Ahmadinejad told a crow of thousands in Orumiyeh in northwestern Iran. Ahmadinejad said enemies of the country were trying to stir up differences among the Iranian people, but "I tell them: you are wrong. The Iranian nation is united." Ahmadinejad criticized a White House rebuff of his offer for a televised debate with President George W. Bush. "They say they support dialogue and the free flow of information. But when debate was proposed, they avoided and opposed it."
