I don't think libya can be considered a success since the end result is a country with almost no oil revenue and because of that, almost zero investment in education, internal security and its own economy. its not that it will take libya a few years to stabilize, its that it will take it a few years to become another current Iraq. its already becoming a major terrorist greenhouse and with further decline in quality of life and lack of education, this trend will just continue to rise.
Yemen is basically the same situation, being a major source of terrorists that fight in iraq and syria, and its only a matter of time before it will be ran over by the same terrorists itself.
Egypt has exactly the same regime, only with a few thousands people dead, ~50 Billion USD in lost revenues and a semi terrorist controlled state in sinai. i find it extremely hard to believe things wont escalate again in the future with such poor living conditions.
Next in the Arab "spring"/domino will be Lebanon which i am surprised still stands. i predicted more than a year ago it will fall within 6 months, but i guess Assad did manage to put out a fight in syria. if Assad steps down, it doesn't matter who or what entity replace him, lebanon will fall soon after since its economical situation is beyond bad and the influx of syrian refugees didn't help. next will probably be jordan that will see its palestine rebellion. back in the day king hussein managed to keep it down by killing dozen of thousands palestines, i am not too sure it will be able to fight off both palestines and whatever other made up "nationality", ethnicity or "idealogoy" that might join them.
Btw, one of the things that are hardly being mentioned about the "Arab Spring" is the living conditions of women in those countries. those rebellions unleashed the repressed sexual frustration of men in those countries that was obvious to anyone who ever been in egypt/jordan/yemen/libya and walked its streets (its almost the first thing anyone who've been in those countries mention, be him israeli, american or european. i have only been in egypt, lebanon and jordan, but i got the impression it was exactly the same all over the Arab ME). men in those countries turned into animals and rape and/or sexual harassment rates got skyrocketed, even without considering the cases that were done as tools of wars.
