It appears reasonably certain to me now that the 1979 Islamic Revolution was driven by Western/Zionist forces. The immediate result of the revolution was the long bloody fratricidal Iran Iraq war that weakened both sides and which strengthened and enriched Israel. The war lasted for 8 years and Iran was supplied with huge quantities of weapons and spares by Israel. This increased the profitability of the Jewish owned American military equipment manufacturers. Remember the Iran Contra Affair ? This covert operation was initiated by Mossad and involved a diverse set of figures such as David Kimche (Mossad), Adnan Khashoggi (Saudi Billionaire and CIA and Mossad operative), Manuch Ghorbanifar (Iranian covert operative) , Miles Copeland (CIA) and others. Estimates of casualties in the war vary between 500,000 to 1.5 million.
It is possible that Ayatollah Khomeini was the son of Englishman William Williamson who was an adventurer who went native and converted to Islam. Williamson played a significant role in negotiations with Western Oil companies and Middle Eastern rulers. Remember Khomeini was comfortably ensconced in Rothschild's Paris prior to being flown into Tehran by Air France when the Shah was removed. Iran's affairs have been controlled by Western powers and by oil companies especially the Anglo Persian Oil Company which later called itself BP.
