Yet if Trump has any faith that those assembled, vile 9/11 Saudis will actually listen to him and take action against the barbaric jihadists they motivated and financed, then he is badly deluded. hopefully there was some consideration given to the prospect of just who will come in possession of these sophisticated weapons when the Saudi royals become desert dust. Also the cash had better be up front.
The Sunni Saudis have a bigger worry and threat now-Shittes
from Iran with billions of dollars from Obama who want to dominate and control the Islamic world.
The Saudi Royals are already basically the puppets of radical Wahhabi clerics, so even with the royals in power these weapons systems will eventually find their way into the hands of jihadis. The clerics and the royals have a pact: the royals give them money to finance extremist causes abroad, in return the clerics legitimate the royals in the eyes of the pious masses, who keep the peace in Saudi Arabia (for now).
