Why is it necessary to be a “saint” to lead a country and maintain the peace?
Mossadegh did nothing good, bottom line. Why are you defending him? He destabilized Iran and stole from western oil companies that were helping his country stay afloat. He was a friend of the Soviets.
No, the point is that the leftists were allowed to help the Islamists stir up the “people” through their usual tactics of class warfare, to induce the removal of the rightful shah and establish an Islamic tyranny in its place. Whatever the last Shah did (including the establishment of SAVAK) was a reaction to that insurrection to keep the peace and keep a monster at bay. But you seem to want to fight the propaganda war of the Islamists and leftists for them.
