It is hard to drill this in the mind of people who grew up under stable governments, but dictators have this terrible habit of sacrificing prosperity to gain control (often sacrificing the former without gaining the later). Being a dictator and surrounded by yes-man, they also tend to act less rationally and less predictably than your average democratic leader.

History is full of kings who started terrible wars and got their countries screwed in the process. You can't apply game theory this kind of people.
