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.

I don't intend this as a drive-by zinger, far from it, but I think you're being hopelessly optimistic. Every country with the science and engineering muscle to make it happen will be pursuing a nuclear program. NATO, former Warsaw Pact, some assholes who managed to cobble together a broadly recognized country by virtue of force of will, you name it. They're all going to be seeking to create nuclear weapons.
