This strikes me as your regular U.S. citizen who has been fed with American Media. As someone who is living in the "region" and was affected by the chain of events that happened since the starting of the Tunisian revolution let me tell you that you are quite misinformed about what happened in reality.

Gaddafi was not toppled because he was going to kill civilians. In fact, it is the other way around. Gaddafi has been killing his opposing politicians for decades. This happened with the best knowledge of his US, EU friends at the time and at really a ridiculous and holocaustic level.

The time the US intervened was when he was going to "truly" protect his country or power from real armed extremists.

If you think the US intervene for the sake of "humans" then you are gullible to your media. The US has been actively intervening in the middle east which resulted in countless (hundreds of thousands) of people and children dying directly from US fire.

There are thousands of people dying from hunger every day. The cost to feed them is certainly much less than the cost of wars the US has engaged. But the US will not help these "black" guys despite having the food, infrastructure and money.

The US only intervenes in countries where there are strategic resources; or to help its allies ( israel / south korea ).
