GP is missing one very relevant example of Libya.
Gaddafi was persuaded by the west to abandon his nuclear programme, and 8 years later he was dead in a ditch.
Also, you probably mean "unleash".
I do disagree with your premise that Gaddafi’s death was a natural consequence of the Western intervention. Whilst watching the events unfold at the time, I’d say he would be ousted and killed irrespectively of any intervention — either by the populace or by the various factions vying for power.
