If there aren't constitutional mechanisms in place for peaceful transfer of power-- along with a tradition of mostly following the norms and conventions around

If there aren't constitutional mechanisms in place for peaceful transfer of power-- along with a tradition of mostly following the norms and conventions around the constitution-- it can all go wrong pretty quickly. People may get very frustrated with democratic governments, but the mechanisms that well established democracies have for the peaceful transfer of power offer a much needed release valve on this sort of pressure. But it takes time to establish the foundations for this. Heck, the US had been around for most of a century and still had a failed revolution (well, it's called a the Civil War, but that's mostly because it failed. I'm sure if the US South had won, they would have viewed it very much as a successful revolution in the same way the original colonies did when they seceded from Great Britain. Yes, there are subtle differences-- Great Britain was somewhat of an absentee overseer, and colonies are not quite the same as states. Admittedly this makes the gray area resolve closer to Civil War.)
