If you’re the Saudi Crown Prince how much could you care that CornPop and the US decided you’re immune. Of course, you’re immune.
You could damn near cripple the world in a week. Giving a damn about Khashoggi. Biden, et al certainly ain’t high on the list of anything
Khashoggi was no friend of the U.S.
The Saudi’s kill a lot of their own citizens. It’s a brutal part of the world, some of them probably earned a brutal early deaths (terrorists) and some didn’t (dissidents). The only thing that makes Khashoggi different is that he was a journalist who published in the Washington Post. That makes his death the only outrageous and tragic one of all those many, many murders the Saudis commit on their own citizens.
