No, I meant the opposite (well, I think some South American countries did, but I'm no expert and still ambivalent on the Chavez countercoup). A revolution actually happening is very bad. But the threat of a revolution keeps politicians in check; occasional revolutions are better than letting dictators run free because they know there won't be one.

I would nominate as an example the French Restauration; after a series of revolutions, the restored French monarchy moved towards constitutionalism and generally more freedom.
