Riots Update

Now as the Libyans continue to riot, I have to see that the fall of communism in 1989 is like the Arab Revolutions recently, especially the Romanian revolution. What happened? Like the Romanians who  kicked out their president Nicolae Ceaușescu in a bloody revolution, the Libyan rebels, with the support of the tribes, are fighting against the government of Gadaffi.  I don't see why the Libyan president Gaddafi has not resigned yet. Perhaps he need to resign so he can flee somewhere to retire. Where is the end?
