Those who insulted the Iranian nation and set back Irans movement for progress for several years must apologise, Ahmadinejad said at a rally in the eastern town of Rashtkhar. His comments were aired on state television and carried by the official news agency.
You must bow down to the greatness of the Iranian nation, he said, addressing the West.
He added that if the United States continued to seek to use bullying tactics then every nation of the world would chant Death to America and Death to Israel.
If you do not return to monotheism and worshipping god and refuse to accept justice then you will burn in the fire of the nations fury, Ahmadinejad said.
He once again accused the West of launching a psychological war against Iran.
On Tuesday, Ahmadinejad declared that Iran had joined the Nuclear Club.
I officially announce that Iran has joined the worlds nuclear countries, Ahmadinejad said in a speech that was broadcast on state television.
The UN Security Council adopted a Presidential Statement unanimously on March 29 giving Iran 30 days to suspend all of its uranium enrichment activities and resume its cooperation with the International Atomic Energy Agency.
