I wouldn't post this piece except that it was authored by one of the world's most knowledgeable journalists. He seems to suggest without qualification that the US had opposed the Saudi support and sponsorship of terrorist armies trying to overthrow the Syrian government.
Nearly a month ago, as I’ve written elsewhere, a top Middle East source close to the House of Saud told me: “The CIA is very displeased with the firing of [former Crown Prince] Mohammad bin Nayef. Mohammad bin Salman is regarded as sponsoring terrorism. In April 2014 the entire royal families of the UAE and Saudi Arabia were to be ousted by the US over terrorism. A compromise was worked out that Nayef would take over running the kingdom to stop it.”

Although not anti-capitalist, I recommend "Bernhard's" website, Moon of Alabama including the comments section, for excellent speculations about all happenings behind the geopolitical scenes as portrayed by the lies of media corporations. See the article on Saudi Arabia posted on the website that is related to this article.
