Iranian President Mahmoud Ahmadinejad launched into one of his greatest tirades at Washington on Sunday, November 3, saying the U.S. would be expelled from the Middle East for threatening the country's nuclear program.

During his visit to New York for the United Nations General Assembly late last month, Ahmadinejad went on a P.R. mission in sit-down interviews with several news outlets ranging from PBS to Fox News. He angered many Americans and triggered a walkout by the U.S. delegation at the U.N., however, when he raised the theory of the 9/11 terrorist attacks being carried out by the U.S. government.

On Sunday, he launched again into his 9/11 scepticism. "We have hundreds of unanswered questions about the September 11 incident to which they should respond, and we will not back down on this," Ahmadinejad said. "If they claim 3,000 people were killed on September 11, [the perpetrators] should be identified and executed. We will even help in their arrest provided they present evidence, but will not accept whatever Bush and Obama say," The Hill cited him as saying.
