IRANIAN President Mahmoud Ahmadinejad today responded to a harsh verbal attack from George W. Bush by saying the US President was "nothing" compared to God's will. "I am telling him (Bush) that all the world is threatening you since the general path that the world is taking is towards worshipping God and divinity," Mr Ahmadinejad told a conference in Tehran. "This massive stream is moving and you are nothing in comparison to God's will."Bush yesterday branded Iran's leaders tyrants as dangerous as al-Qaeda terrorists and said they must not be allowed to get nuclear weapons — "the tools of mass murder".
