Dictators cause the world's worst problems: all the collapsed states, and all the devastated economies. All the vapid cases of corruption, grand theft, and naked plunder of the treasury are caused by dictators, leaving in their wake trails of wanton destruction, horrendous carnage and human debris.
People who live in hermit states like North Korea, Burma, and Cuba already suffer from global isolation. Fed on a diet of propaganda, they don't know what's happening inside their borders or outside of them. By increasing their seclusion, sanctions make it easier for dictators to blame external enemies for a country's suffering.
One of the dark truths about dictators - and it applies to Gaddafi - is that on some level, they love their people. But it is a strange love. It says, 'I love you for me; I don't love you for you.' That rhymes with a certain kind of Libyan father who was always certain about what was good for those around him. Those fathers lose in the end.
