What goes around comes around—just not always in the ways you'd expect. Syrian rebels are being supplied with weapons in a multinational aid effort largely funded by Qatar. But in a crazy plot twist, the weapons originated with Muammar Gaddafi's totalitarian government in Libya. At the height of his power, Gaddafi kept stockpiles of arms to send to people fighting governments he didn't like. But in post-Gaddafi Libya the tables have turned, and now the very rebels who ousted the late dictator are using his weapons to help efforts he would have loathed. Talk about revenge.
