The death of King Abdullah in January 2015 confirmed the contradictions at work in Saudi politics. The architect of Abdullah's destructive policies, President of the Royal Court Khalid al-Tuwaijri, was immediately dismissed. Tuwaijri was the key player in foreign intrigues--to subvert the Egyptian revolution, to send in the troops to crush the uprising in Bahrain, to finance ISIL in Syria in the early stages of the civil war along his previous 'ally' Prince Bandar bin Sultan.
As Abdullah lay dying, the Zaidi Shia Houthis in Yemen were occupying the presidential palace in Sana, a plan plotted by former Yemeni dictator Saleh and the United Arab Emirates (Saudi allies), keen to undermine the democratic transformation of Yemen that Islah, the Yemeni Muslim Brotherhood, was trying to effect.
The entire focus of Abdullah's foreign policy after 2011 was to stop the Arab spring in its tracks in Tunisia and Egypt, bribe their leaders with Saudi billions, and crush all forces capable of mounting an effective opposition in the Gulf States. Everything else, including the rise of Saudi's foremost regional rival Iran, became subservient to that paramount aim to crush democratic political Islam.
Obsession with Iran
The elephant in the room here is Iran. Why are the Saudis sooo hostile to Iran? Iran has never publically called for their overthrow. It has made countless offers of dialogue over many long decades. It's more a question of the Saudis trying to use Sunni-Shia sectarianism to hide their irrelevance to the Muslim world (and the world at large).
When the US figures this out, the days of the Saudi dictatorship/ monarchy will be numbered. Iran will take its place as the more reliable, sensible--Islamic--state in the region, the only state not afraid of genuine democracy.
The Shia revolution in Iran had echoes in the Sunni world from the start in 1979. It inspired a young Egyptian Muslim Brother, Essam el-Erian (now imprisoned Freedom and Justice Party vice-chairman and MP), to say at that time, "Young people believe Islam is the solution to the ills in society after the failure of western democracy, socialism and communism to address the political and socio-economic difficulties." It prompted Saudi rebels to occupy the Kaaba that same year in an attempt to spark revolution, Syrian Islamists to rise against their secular dictator Hafez al-Assad in 1980, and future al-Qaeda leader Ayman Zawahiri to conspire to assassinate Egyptian president Sadat in 1981.
Pakistan adds its two cents
Most of the terrorists (those implicated in the 9/11 hijackings, the foreign fighters in Afghanistan in the 1980s and now in Syria/ Iraq) were/are understandably disaffected Saudis, rich on oil wealth, educated at western universities (or unemployed), yet disgusted by the Saudi alliance with imperialism (and by implication, with Israel) that was blessed by the Wahhabi establishment--so-called neo-Wahhabis. They found allies in their Pakistani brothers, betrayed, first, at 'independence' when the British handed Muslim Kashmir over to India, and then again when Reagan declared 'victory' over the Evil (Soviet) Empire in 1990 and decided they were really terrorists after all.
CIA analysts coined a term for this type of counterproductive outcome resulting from attempts to manipulate political developments--"blowback"--in its internal analysis of its own orchestration of the 1953 coup in Iran, warning of future anti-Americanism as a result of the coup. The neo-Wahhabis provide another, even more serious instance of blowback, where the revolutionaries, angry with Muslim official complicity with imperialism, started using strategies of revolution and the arms of the imperialists against both the US and their own leaders and peoples.
Egypt was a ray of hope
Like the Iranians, the Egyptian Muslim Brotherhood tried hard to square the circle with the Saudis but Saudi chauvinism trumps belief. The willingness of the Saudis to sacrifice thousands of Egyptian Muslims is shocking, though not out of character. Remember the1979 seige of Mecca by French Special Forces, who killed hundreds, possible some of the same 'Spetsnaz' who are murdering Muslims on the streets of France today.
