I agree with you that dictatorships are hard to shake off. That's what we saw in the Arab Spring. However, while Burke's conservatism may have been moderate in that he was open to a constitutional monarchy, a dictatorship is just a modern form of monarchy, so those two are "conservative" social arrangements, meaning they're both natural. In short, they're elaborations on the animal dominance hierarchy or pecking order.

So the question is what to do about these dictatorships. I don't argue for a repeat of the French Revolution in all of these cases. Violent regime change isn't necessarily the answer, as we saw with the brief and farcical outbreak of democracy after the collapse of the Soviet Union, and as we saw with Bush's attempt at a neoconservative revolution in Iraq and Afghanistan. I agree with Oswald Spengler's point about the importance of underlying culture, about the ethos and the mythos that provide our cultural identity. Yuval Harari points out how that shared identity enables us to cooperate even with so many strangers in a civilized state.

But these cultures can clash, and what we call liberalism, humanism, progressivism, and so forth grow out of European cultures and revolutions. The same institutions won't be viable in all cultures. Real democracy isn't so palatable in the Middle East, for example, because the requisite humanism conflicts with Islamic absolutism. God's laws take priority over human laws. So that region hasn't been "modernized," which is to say secularized. Europe went through that overall transition, which led to much conflict and trauma and which has led to the economic "progress" of consumerism which threatens the planet.

I should add that "stability" is a hollow ideal. Hell is stable. Stability is about merely what's long-lasting. Bad conditions can be long-lasting. Indeed, the dominance hierarchy as it was expressed in the absolute monarchy was long-lasting and thus stable. Most human societies have reflected that natural, animalistic default, precisely because that arrangement is genetically safe. It ties in with our animal nature, but not so much with our potential to live as autonomous persons. Liberal societies emphasize the humanity of Everyman, and that revolution has its advantages and disadvantages, as I try to spell out in different articles.
