No offense, but it was a terrorist attack by definition right when it happened. But that doesn't really tell us how much planning went into it, and it ignores a basic problem that Obama and neoconservative Republicans don't want to discuss.
Neocon mouthpiece Senator McCain asked a pretty silly question: "Who brings rocket propelled grenades to a protest?" In Libya? Anybody.
Libya has been turned into the Somalia of the Mediterranean thanks to the Obama administration and Republican neocon howlers.
Weapons caches were raided, and the country is overrun with well-armed militias who roam the streets looking for mischief. The Libyan government doesn't want to admit it has no control so you can't believe anything they say.
