The furore over the sexual antics of Donald Trump is preventing much attention being given to the latest batch of leaked emails to and from Hillary Clinton. Most fascinating of these is [a] memo, dated 17 August 2014. There is no ambivalence about who is backing Isis. The memo says: "We need to use our diplomatic and more traditional intelligence assets to bring pressure on the governments of Qatar and Saudi Arabia, which are providing clandestine financial and logistic support to Isis and other radical groups in the region." After 9/11, the US refused to confront these traditional Sunni allies and thereby ensured that the "War on Terror" would fail decisively; 15 years later, al-Qaeda in its different guises is much stronger than it used to be because shadowy state sponsors, without whom it could not have survived, were given a free pass. It is not as if Hillary Clinton as Secretary of State ... did not know what was happening. An earlier WikiLeaks release of a State Department cable sent under her name in December 2009 states that "Saudi Arabia remains a critical financial support base for al-Qaeda, the Taliban, LeT [Lashkar-e-Taiba in Pakistan]." But Saudi complicity with these movements never became a central political issue in the US. Why not? The US did not think it was in its interests to cut its traditional Sunni allies loose and put a great deal of resources into making sure that this did not happen. They brought on side compliant journalists, academics and politicians willing to give overt or covert support to Saudi positions.
