Iran's President Ahmadinejad Wants U.S. Leaders 'Buried' For Threats

Iranian President and notorious firebrand Mahmoud Ahmadinejad unleashed his latest round of insults at the U.S. on Sunday, calling for American leaders to be "buried” for what he claims are threats of violence against Tehran's nuclear program.

"May the undertaker bury you, your table and your body, which has soiled the world," Ahmadinejad said, according to The Associated Press, an unusually harsh statement even for the controversy-loving leader.

Adm. Mike Mulllen, Chairman of the Joint Chiefs of Staff, said in August the use of force against Iran remains a possibility.

"I think the military options have been on the table and remain on the table," he said on NBC’s "Meet the Press." "It's one of the options that the President has…I hope we don't get to that, but it's an important option and it's one that's well understood."

President Obama has also pledged to take a hard line against Iran if the country does not comply with its non-proliferation treaty obligations.

"The United States and the international community seek a resolution to our differences with Iran, and the door remains open to diplomacy should Iran choose to walk through it," Obama said last month in an address to the UN General Assembly. "But the Iranian government must demonstrate a clear and credible commitment, and confirm to the world the peaceful intent of its nuclear program."

Ahmadinejad also took the opportunity on Sunday to once again express doubts about the facts behind the September 11th attacks.

"We have hundreds of unanswered questions about the September 11 incident to which they should respond, and we will not back down on this," he said, in the speech broadcast by state television and English-language Press TV.

"If they claim 3,000 people were killed on September 11, [the perpetrators] should be identified and executed," he added. "We will even help in their arrest provided they present evidence, but will not accept whatever Bush and Obama say."

Ahmadinejad has made similar remarks in the past, most recently at the U.N. last month in which he argued "some segments within the U.S. government orchestrated the attack."

That speech caused the U.S. delegation to walk out of the room in protest, and was immediately decried by Obama.

"For him to make a statement like that was inexcusable," the President told the BBC.
