Speaking to thousands of worshippers during the first Friday prayer of the Muslim holy month of Ramadan, Iran's supreme leader Ayatollah Ali Khamenei said that Bush will be called to account for the U.S.-led invasion of Iraq.
"A day will come that the current U.S. president and officials will be tried in an international supreme court for the catastrophes they caused in Iraq," he said.
"Americans will have to answer for why they don't end occupation of Iraq and why waves of terrorism and insurgency have overwhelmed the country," he added. "It will not be like this forever and some day they will be stopped as happened to Hitler, Saddam and certain other European leaders."
Khamenei mocked the U.S., describing the recent congressional testimony of the top U.S. officials in Iraq as a sign of weakness and the failure of American policy in the war torn country.
"More than four years have past since the occupation of Iraq and today everyone knows that American has failed and is frantically looking for a way out," he said.
In their testimony Gen. David Petraeus and Ambassador Ryan Crocker raised allegations - rejected by Iran - of Iranian meddling in Iraq by financial and military supporting militias and insurgent groups.
Despite U.N. sanctions and efforts to isolate Iran internationally, the country is flourishing, maintained Khamenei.
"Today we are in a better political position compared to four to five years ago," he said. "We have moved forward economically and the spiritual preparedness and happiness of our nation has improved."
"A nation like ours, without an atomic bomb and not as wealthy as these other powerful governments, has foiled a whole series of their conspiracies and forced them to give up and withdraw," he added.
The U.S. accuses Iran of secretly trying to develop nuclear weapons and has called for further international sanctions against the country. Iran denies the charge.
Iran and the U.S. have not had diplomatic relations since Washington cut its ties with Tehran after Iranian students stormed the U.S. embassy there in 1979.
