How far is Saudi Arabia complicit in the Isis takeover of much of northern Iraq, and is it stoking an escalating Sunni-Shia conflict across the Islamic world? Some time before 9/11, Prince Bandar bin Sultan, once the powerful Saudi ambassador in Washington and head of Saudi intelligence until a few months ago, had a revealing and ominous conversation with the head of the British Secret Intelligence Service, MI6, Sir Richard Dearlove. Prince Bandar told him: "The time is not far off in the Middle East, Richard, when it will be literally 'God help the Shia'. More than a billion Sunnis have simply had enough of them."
The fatal moment predicted by Prince Bandar may now have come for many Shia, with Saudi Arabia playing an important role in bringing it about by supporting the anti-Shia jihad in Iraq and Syria. Since the capture of Mosul by the Islamic State of Iraq and the Levant (Isis) on 10 June, Shia women and children have been killed in villages south of Kirkuk, and Shia air force cadets machine-gunned and buried in mass graves near Tikrit.
