You might think this is a rather obvious and simple question top answer. There is only one person to blame for the killings in Libya and that's Muammar Qaddafi, and in terms of beyond well that would be all the other despots etc.
Of course, if you're one of those "all things are the fault of the West" type people then clearly you're going to blame the people that sold the guns instead. However, there is one other person you forgot. The Chairman of the United States Federal Reserve, Ben Bernanke.
Yes, really, honestly, truthfully, there are some people who think that far from so-called "crimes against humanity" being the fault of the mentalist that ordered the indiscriminate shooting of heavy firepower on people, the real fault lies with man that introduced quantitative easing in the US.
Don't believe me? Go and read this then.
Apparently, by flooding the US market with extra-cash when they were strapped, it deflated the dollar meaning the cost of food rose in poor countries like those in North Africa, thus leading to revolution against despot, thus leading to the despot using their guns.... ergo.... the deaths and whatever else are actually not the fault of the despots but are in fact the fault of the person that decided to flooded the US market with cash and thereby reduce the value of the dollar.
It's amazing what utter absurd logic some people will come out with these days in order to satisfy a self-loathing tendency and appease the guilt of the guilty init?
