Washington - US President George W Bush reiterated his pledge that the United States will not allow Iran to develop nuclear weapons in a wide ranging speech on the Middle East Friday.
"For the safety of our people and the peace of the world, America will not allow Iran to develop a nuclear weapon," Bush said at the Saban Center for Middle East Policy at the Brookings Institution.
Bush suggested the US invasion of Iraq to topple Saddam Hussein prompted Iran to slow its nuclear ambitions, only to resume them after the election of President Mahmoud Ahmadinejad in 2006.
"The defeat of Saddam also appears to have changed the calculation of Iran," Bush said.
