It is ironic that Khamenei demanded Obama to apologize for the 1953 Coup D'etat given that: (As I recall going to school in Iran)
Unable to exorcise Mosaddeq's ghost, the Islamic Republic has tried to contain it. High school textbooks allocate twelve pages to Kuchek Khan, four pages to Modarres, another four to Shaykh Nuri, and less than two to Mosaddeq -- about the same as given to Navab Safavi, the Fedayan-e Islam leader. Meanwhile, the mass media elevate Ayatollah [Abul Qasem] Kashani as the real leader of the oil nationalization campaign, depicting Mosaddeq as merely the ayatollah's hanger-on. Even more significant, the regime portrays the 1951-53 period as yet another example of leftist betrayal, arguing that the nationalist movement failed because it was stabbed in the back by the Tudeh [communist party of Iran].(Highly recommended source: Ervand Abrahamian)
If Mosaddeq fell because of a "stab in the back," the stab came not so much from the Left as from the religious Right. From the very beginning, the clerical establishment had arrayed itself against the National Front. Ayatollah Behbehani, the senior cleric in Tehran and the grandson of the famous constitutional leader, had openly sided with the shah. The substantial influx of CIA money into the Tehran bazaar on the eve of the 1953 coup became known as "Behbehani dollars." Even more important, Ayatollah Borujerdi -- a staunch royalist and the leading marja-e taqlid from 1944 until his death in 1961 -- had tried to stem Mosaddeq's popularity by issuing an edict forbidding the clergy from participating in politics. He epitomized the conservative clergy, who claimed to be apolitical but in fact bolstered the royalist regime. Ruhani, Khomeini's main biographer, tries to explain Borujerdi's behavior by claiming that the "imperialists" had planted "agents" around him to isolate him from society.
