Why? Because Libya was stable under Khadaffi (as stable as those kind of places get) and people had it relatively very good. And yet he was portrayed like some Dr. Evil plotting to takeover the world, so that the western masses will cheer when he got toppled and foreign interests get the oil and natural resources.
And the very thing was hailed as a "triumph of democracy" etc (what a democracy, when foreign leaders cheer when an adversary is beaten to a pulp -- gone are the days when even Nazi generals were treated with respect by the western officers when captured).
Well, it didn't last long, now, as predicted, Libya will get to be another unstable, civil-war, dogmatic islam nightmarish country.
