No. No, it definitely is not. Change is usually slow and orderly. By voicing your opinion, by using diplomacy, by outside influences, the people itself, politics, etc. Not even during a revolution are things abrupt and chaotic, mainly because all the underlying systems remain intact and only the head is changed.
Unless some warmongering country from across the world suddenly wants your oil and bombs you back to the middle ages. Then it's fast, abrupt and chaotic.
Either you are being sarcastic and i'm missing the point or you are serious. In which case I say that changes in regimes are not often peaceful, this one is made worse by the fact that we tore down the underlying systems and the impoverishment in the area. A unique area that has as many factions as people.
