Getting Treasury Secretary Manuchin to withdraw from the Riyadh Economic Conference was like pulling teeth. Even after virtually every other national, supranational agency, media organ and, investment bank had done so. And Trump continues to waffle and punt the issue.
Let's be clear that there is 'high confidence', which in diplomatic terms means it is a moral certainty, that MbS ordered the torture and murder of Khashoggi in his Turkish Consulate as a message to Saudi media critics world wide. That message is there is no where you can hide from me and my vengeance. He was the ONLY one with the means, motive and, opportunity.
The reluctance of the Trump Whitehouse to acknowledge the obvious comes from one doctrinal imperative and from one proponent in the Administration. The proponent is Jared Kushner and doctrine is that of containment of Iran which is deemed to be an existential threat to Israel. Kushner in first and foremost a citizen of Zion; the political and geographical manifestation of Jewish nationalism.
In this construct Saudi Arabia/Sunni is seen to be the counterweight to Iranian/Shia dominance of the Middle East. Hence Yemen, Quatar, Syria are all drawn into spheres of influence. The whole woven narrative of 'demonizing' Iran and 'angelizing' Saudi Arabia stems from this premise. Trump seems totally bamboozled and deferential to his Son-in-Law on the issue and MbS is seen as a reliable and malleable intrument in its execution. That quilt in now unravelling.
The truth is the whole region, Saudi Arabia, Iran, Israel included, is a nest of vipers. And Trump has managed to botch this whole sordid affair to the point that it is discrediting his reputation after significant victories in SCOTUS and federal courts, and, in the economy.
It is time to cut loose MsB (and Kushner.. make him Ambassador to Israel and get him out of the Whitehouse). The Crown Prince is finished inside and outside the Kingdom. Trump has to get out in front of this or it will effect his ability to keep the House of Representatives. And that would provide a platform for the Dems to torment him for the next two years.
