Saudi Arabia's million barrel a day output, plus its strategic location in the Middle East, means the West must pay obeisance to the regional head-choppers. The Saudis have ... threatened to sell billions of dollars of their US assets if Congress passes a bill allowing the Saudi government to be held responsible in American courts for the crimes against humanity of 9/11. And that, indeed, is the foundation of the US-Saudi mess right now. Of the 19 hijackers involved in 9/11, 15 were Saudis, a fact diplomatically ignored in the years immediately following the attacks. The Saudis bankrolled the Taliban for many years. The Americans believe - rightly - that Isis itself today receives much support from within Saudi Arabia, though they haven't gone quite so far as to say the government is behind this. But ... the country's massive oil reserves, its million barrels a day output, strategic location and control of Sunni Muslim finances, means that the West has got to go on paying obeisance. The real problem is that - after years of fantasy in which, against all the evidence, the Americans persuaded themselves that the Saudis were a 'force for moderation' in the Middle East - the Obama administration has decided that Shiite Iran and the huge influence it exerts over the Shiite governments of Iraq and Syria (and over the Shiite Hizballah in Lebanon) is a better bet than the Sunni Salafists of Arabia. It would be good to know what the censored 28 pages of the official US 9/11 report said about the Saudis. Any more talk of withdrawing billions of US assets might just persuade the Americans to ... let us take a peek into those secrets.
