(Excerpted from Chapter 10: The Iran/Iraq War: Big Oil & Their Bankers…)
The irrational deep-seated hatred which the Anglo-American foreign policy establishment holds towards Iran is rooted in the 1979 Iranian Revolution, which overthrew the Four Horsemen stooge Shah and nationalized Iran’s oil and banking industries.
The Eight Families banking cabal much preferred the mullahs to the leftists. By 1982 CIA and MI6 were passing targeting information to the Ayatollah aimed at Iranian leftist groups like the Tudeh Party, the National Front and the People’s Mujahadeen. The mullahs unleashed a reign of terror, assassinating over 4,000 Tudeh Party leaders, while torturing and imprisoning over 10,000 Tudeh members and supporters. In 1989 many of those imprisoned were sentenced to death. 
Khomeini banned Tudeh, terming them “Marxist satanic elements” – something even the Shah hadn’t done. The Tudeh Party spearheaded the Iranian Revolution through their Committee of 60 oilfield strikes in Khuzistan. The party earlier ushered in Prime Minister Mohammed Mossadegh, whose attempts to wrest better terms from the Four Horsemen-controlled Iranian Consortium made him the target of a successful BP-financed coup in 1953.
The US was now once again helping Islamic extremists, this time to exterminate the Iranian left. One US official assured reporters that the executions “would not hinder the warming of US/Iran relations”.  Big Oil was dealing with the Ayatollah as well, secretly shipping Iranian crude to Saudi Arabia for refining.
The Israeli Mossad was walking the same high-wire in their country, where in 1978 it allowed the fundamentalist Hamas to become the only Palestinian group registered in Israel. Within a decade Hamas leader Sheik Ahmed Yassin had built a powerful organization that ruled the Gaza Strip under Israeli watch. 
The Israelis found Hamas a convenient bludgeon which they could deploy against Yasser Arafat whose Palestinian Authority had emerged from Fatah and the PLO, both of which put forth a secular left of center political agenda based on Arab unity and nationalism.
Hamas has a much different agenda. They are Islamists whose goal is to set up an Islamic state with funding from the undemocratic right-wing GCC sheikdoms, especially the House of Saud. Hamas regularly receives funds from the Saudis without intervention by the Israelis, while money bound for the PLO is routinely seized by Israeli authorities. Israeli Prime Minister Ariel Sharon played a critical role in the founding of Hamas in 1988, when his Likud Party doled out 800 licenses to Islamists in the occupied Palestinian territories of Gaza and the West Bank. The right-wing Israeli Likud uses Hamas to sew division among the Palestinians.
The Saudis favor Hamas since their interests are firmly aligned with those of the international bankers and the Four Horsemen. The Saudis prefer fundamentalist groups that talk of “infidels” and “the decadence of Western culture”, to those more radical nationalist groups who rail against the injustice of neo-liberal globalization, a system from which the House of Saud derives its vast wealth. After the Gulf War the House of Saud cut funding to the PLO to punish Arafat for his opposition to the US bombing of Iraq, while the Saudis continued to fund Hamas.  Many House of Saud members are members of the secret society Muslim Brotherhood-Benoist-Mechin.
