Bush on Iran
Iran remains a threat to the world despite new intelligence saying the country may not be building nuclear weapons, the US president says.
Mr Bush said the report released on Monday was a "warning signal" and his view that a nuclear Iran would be a danger "hasn't changed". The president stressed that Iran was still trying to enrich uranium and could restart its weapons programme . Tehran has denied continued accusations that it is developing nuclear weapons. Mr Bush said the new National Intelligence Estimate (NIE) was "an opportunity for us to rally the international community" to pressure the Iranian regime to suspend its efforts to enrich uranium - a key part of the process in making a nuclear bomb. "I view this report as a warning signal that they had the programme , they halted the programme ," Mr Bush told a news conference. "The reason why it's a warning signal is they could restart it." Iran was dangerous, Iran is dangerous and Iran will be dangerous if they have the know-how to make a nuclear weapon," Mr Bush said.
