What has been an open secret across the Arab world is not a secret anymore even in the US: What happened last month in the deep recesses of the House of Saud with the ascension of Crown Prince Mohammad bin Salman, aka MBS, was in fact a white coup.

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."
