Speaking at Georgetown University, former President Bill "Bubba" Clinton said that the Islamic State is the "most interesting non-governmental organization today."
"Arguably the most interesting non-governmental organization today, which proves the importance of inclusion by its short-comings but is formidable, is ISIS.
"ISIS is a terrorist organization, an NGO, trying to become a state. That is, they don't recognize any of the boundaries of the Middle Eastern countries as legitimate. They were all established, drawn largely by Westerners after the collapse of the Ottoman Empire in World War I.
"And so when they go capture a place, they set up their own judicial system, they set up their own rule making, they set up whatever their social services are going to be. And the only thing is, you can't disagree with them, or they'll kill you," Clinton said.
