United has failed to destroy the Iranian Revolution. That was President Ahmadinejad message marking the 30th anniversary of the Islamic Regime in Tehran.
Iranians are celebrating 30 years of "freedom from tyranny" - the ousting in 1979 of the Shah as an American puppet dictator.
Ahmadinejad paid visit to Khomeini's mausoleum in Tehran and offer his prayers to founder.
"The Islamic Revolution is the result of sacrifices made by martyrs," read a banner inscribed with one of Khomeini's famous quotes.
The President said in tribute to the founder of the Islamic Republic of Iran: The Islamic Revolution is very much "alive and kicking". And it will "continue until full peace and justice are established".
Iranians are holding 10 days of celebrations marking the 30th anniversary of the overthrow of the US-backed Reza Shah, who ruled the country for 40 years and then fled just two weeks before Ayatollah's "thunderous" return on 9:33am February 1, 1979.
Immediately the revolutionary leader branded the United States as the "Great Satan".
In homage, the current Supreme Leader of Iran, Ayatollah Ali Khamenei said that the Iranians will "guard the great legacy and principles" of the founder of Revolution.
President Ahmadinejad said Iran would export the Revolution to other countries. The ideals of the founder would be expanded "internationally". The Islamic Revolution is "not limited to Iranian borders", said Mr Ahmadinejad.
