Dictators, unlike Democrats, depend on a small coterie to sustain their power. These backers, generally drawn from the military, the senior civil service, and family or clan members, have a synergistic relationship with their dictator. The dictator delivers opportunities for them to become rich, and they protect him from being overthrown.

There are lots of people shaping decisions, and so if we want to predict correctly, we have to pay attention to everybody who is trying to shape the outcome, not just the people at the pinnacle of the decision-making pyramid.
