Iran to walk away from NPT?

Yet another threat from Iran's President. Let's take him at his word -- time to pull up our sleeves.

Iran's president warned on Saturday that Iran could withdraw from the Nuclear Nonproliferation Treaty if international pressure increased over its nuclear program.

A demonstrator in Tehran walked over a burning representation of the American flag Saturday as tens of thousands celebrated the 27th anniversary of the Islamic Revolution.

His threat was a significant escalation of the government's previous position that it would only stop complying with spot inspections of military installations and sites it has not declared to be part of its nuclear program. The warning also raised the specter that Iran was considering following a strategy set by North Korea three years ago.

In a speech to tens of thousand of demonstrators who had gathered to mark the 27th anniversary of the Islamic revolution, President Mahmoud Ahmadinejad also staked out a broader path of resistance if penalties are imposed against Iran.

Evoking the possibility of penalties and international ostracism, he insisted that the country would continue its nuclear activities and urged Iranians to brace for tough times.

"The Islamic Republic has continued its program within the framework of the International Atomic Energy Agency and the nonproliferation treaty," he said in the speech, which was broadcast live on state television. "But if we see that you want to use the NPT regulations to deprive us of our rights, know that the people will revise their policy in this regard."

"I ask our dear people to prepare themselves for a great struggle," he added, evoking the possibility of international penalties. "Fasten your seat belts and pull up your sleeves."
