MBS has a free run for now . He was appointed out of the line of succession . So we can really expect someone to put a bullet to his head if the west is displeased with him .Saudis are becoming liberal by far now.
Have you seen changes MBS is bringing in Saudi lifestyle.
Women too are being granted more rights gradually .
Cinema, alcohol, party and what not is happening in Saudi these days.
( Ofcourse not full mainstream but gradually)
He will take Saudi to much more liberal country than we could have ever imagined.
What I was trying to convey is that there are a set of hardliners who are patronised and eugolised within those countries who will choose to support a hardliner than someone who would dilute the religious ways .
