Much as the military in Egypt took over from the King in the 50’s and then one of their own (Nasser) after the 6 day war failure by replacing him with an air force colonel (Sadat). Qaddaffi was one of the 4 colonels in the Libyan army that coup’ed their King in the late 60’s, so the military “taking over” now would be much like a change in CEO at a company here in the states — same outfit running the show, but a new face in front of the camera.
