there is one thing about Saudi I am curious about though, which is how well assured MBS's ascension to the throne is once the old king, who is apparently well into dementia, finally passes.
Eversince the death of Ibn Saud, the throne has passed from brother to brother among his sons. There was never, has never been any agreed upon plan for what happens when the last direct heir of Ibn Saud died. We are fast approaching that point. This is what has made MBS possible in a way. If more of his uncles were still alive, he would know he had no path to the throne so what he is doing to consolidate his personal power would be pointless, but I believe there is only one uncle left now - so he sees the throne as close enough to sieze. I don't know much about the uncle other than that MBS has had him arrested at least once, so there is probably no love lost there now. So the question is what kind of political operative is old uncle Ahmed? Is he content to just slip away into a posh Arabian sunset and leave the field to his nephew, or can/will he or his people be manuevering to block MBS's path to the throne when the time comes, and/or do/will they have any capacity to do that? And even if Ahmed's clan stands clear, there are at least 100 other grandsons of old Saud who may figure they have just as much 'right' to the throne as MBS. Are they all fat and happy enough? Is there some block of them with ambition? Will there be a knife in the dark one night in Riyadh? Who knows? I certainly hope US intelligence is working these questions for Biden though.
