Morton @21 is of the opinion AIUI that the people are as or more fundamentalist than the regime and view the corruption as an affront to islam, the correction being more islam. Maybe so.

Could it be that they love islam (no accounting for taste), but have figured out that it wont work as a governing structure? All I know about the scheme is what I read on the internets but part of it is a call for devotion to the Almighty, against which most would have no objection. Other parts, not so much. Now if they were to figure out the parts that work for the ages and develop some tolerance for other disciplines, they might learn to play well with others, including their own brethren.
