I've been thinking about the Egyptians. IIRC, time was, maybe before Khaddafi's time when Naser was in charge in Egypt, he had some designs on the Cyrenaican region of Libya. If I was in charge of the Egyptian military right now, I'd find it hard not to think of how popular I'd be to take a nice drive over to Brenghazi with some of those M1A2's I have.
That makes a lot of sense. In land miles, Benghazi's closer to Egypt than to Tripoli. If the eastern rebels asked to be annexed Egypt could sure use the oil.
