Salman is a Saud. Sauds are members of a vanishing species, major arab royalty. They behave as arabs and as autocratic royalty. We can either use them or we can disdain them but we cannot change them. If we get virtuous and shun them we will pay a large price in the Middle East and not influence their methods and characteristics one whit. If we get the Sauds replaced it is the nature of Arabs that the replacement will be less virtuous than the Sauds and much less useful to us.
The original Khashoggi are of Turkish heritage, and married into Saudi royalty. Uncle Adnan was the essential arms broker until he forgot to pay off some royals. As for Jamal, he got the first in-depth interview with Osama Bin Laden after the creation of Al Qaeda in August 1988. Jamal has played footsie with Islamists of various stripes for years, and as noted has had a long established relationship with the Muslim Brotherhood. It was one reason he would never return to Saudi Arabia, and it is the reason he is not welcomed in Egypt. He is of course loved by the Washington Post and the US “liberal” establishment.
