As with most of the things in the world the topic is not black and white.
Working in the company covering most of the world I had opportunities to visit Egypt, UAE, all of FSU Asian states and most of FSU european-part countries, I have collegues working there as well as in KSA, Kuwait, Qatar.
It is very difficult to succeed in establishing democracy somewhere where it never existed. You don't have the structure, you don't have the right bureacrats with a proper mindset and you population mindset is very different even from us in Russia.
You can't bomb people into democracy – see Lybia, Iraq, Afghanistan, etc.
I can tell you that my SA colleagues have very high opinion on prince Salman and they see him as a reformer and progressive ruler, while we see him running bloody adventure in Yemen and cutting journalists to pieces.
Tunisia was lucky bcs they at least didn't have too much of tribals/religion/nationalism problems we see in other failed Arabian spring countries…but other reasons for failure are there.
People will always go for changes when they're fed up with current government,and we always hope that changes will be for better – these were my hopes in 1991 and in 1993. When new rulers fail to deliver (99% of cases) it all starts again, and depending on number of coubtry problems you have a new revolution or dictatorship.
Most Arabian dictatorship have high level of both state and everyday corruption, you see it starting right in the airport….interesting that under Stalin corruption was very low, as some people were just afraid and others were not even thinking about doing something illegal.
When you found yourself on the wrong side of the state, there was a very high chance to receive a punishment not comparable with what you hoped to get by taking bribes.
I still remember that in 70s when I was a kid we could play till late night, going around the city, leaving keys under the door and nobody was afraid….looks like a SF nowadays.
On the other hand even death penalty in Chnia is not stopping people from taking enormous bribes now.
