Mahmoud Ahmadinejad has said US allegations of an Iranian assassination plot resemble its claims about weapons of mass destruction that formed the basis for the 2003 invasion of Iraq, and would prove to be equally untrue.
The Iranian president suggested that the US aimed to cause a rift between Tehran and Saudi Arabia that would help Washington dominate the oil-rich Gulf and had fabricated the plot of an Iranian seeking to kill the Saudi ambassador to America.
"In the past the US administration claimed there were weapons of mass destruction in Iraq. They said it so strongly, they offered and presented documentations and everyone said: 'Yes, we believe in you. We buy it,'" Ahmadinejad said in a live interview on al-Jazeera television on Monday evening.
"Now is everyone asking them, were those claims true? Did they find any weapon of mass destruction in Iraq? They fabricated a bunch of papers. Is that a difficult thing to do?
"The truth will be revealed ultimately and there will be no problem for us at that time," he added.
Barack Obama hopes the alleged foiled plot will lead to tighter sanctions against Iran – already under several rounds of UN measures over its nuclear programme. The Us president has repeatedly said that all options were on the table to deal with the Islamic republic, a tacit threat of possible military action.
When asked whether he thought Iran and the US were on an inevitable "collision course" towards military conflict, Ahmadinejad replied: "I don't think so. I think that there are some people in the US administration who want this to happen but I think there are wise people in the US administration who know they shouldn't do such a thing."
Nevertheless, Ahmad Reza Pourdastan, commander of Iranian ground forces, said his troops were "fully prepared and ready to give a quick response to any aggression on Iran's soil".
