Since VRWC is slow to response on my errors (not saying he is well informed about that)

. I will inform the truth that he was never ordered to be assassinated. In correction: he was ordered to be deposed by way of bribing his political colleagues and his former minister of interior name Fazlollah Zahedi (who was a retired General). They also pump a million of dollars to infiltrate the media, the Shaban Jafar, and do anything necessary to put the popular Tudeh Party and Ayatollah Abol-Ghasem Kashani under suspicion who were closely allied with the National Front of Iran (Dr. Mossadegh's Party). The Shah later came into the scene because of some dispute on where should the money ought to be allocated. He wanted a whole stake of the oil for himself and his cronies, but instead had to compromise with the multinationals.
He was not assasinated, but died in house arrest.
