Here’s a reflection: the value proposition of democracy is that it provides for a peaceful transfer of power, once an incumbent regime loses its political legitimacy. If you have a working democracy you don’t need revolutions to get rid of incompetent leadership. As Enoch Powell said, “every politician’s career ends in failure” (unless they die unexpectedly): in a democracy they agree to step down, and life goes on.

But when you get a faction, party, or regime that no longer subscribes to the idea of democracy and refuses to back down gracefully, you get back the old problems: pressure for change builds up and when it erupts the effects can be devastating and unpleasant–especially, as we’ve had a crash-course reminder in recent years, when the tools of communication make it really easy for dangerous demagogues to draw a following.
