So this Arab uprising, up to now has only been capable of overthrowing rulers who belong to the old age[ forgive me if something in here hurts]. These were the guys who didn't knew how to communicate with the mass media. During the early periods of their rule the advanced computers, advanced military and scientific technology was still developing, and the age of mass media like twitter, facebook or youtube were not even thought of. So its no wonder for me that these guys were not able to withstand strong oppositions which were mainly led by the youth who in nature are strong, independent and violent.
My take on individuals like Gadafi, Bin Ali and Mubarak is that, these kind of guys will continue to appear in the future whatever the steps and changes that the world as a whole has taken to avoid such situations. It's because they are individuals who by whatever means try to excel in what they do, its in their normal instincts to lower the opinion of those he/she deems does not deserve to live a happily endowed life. Some may call these kind of guys psychopaths or even mad dogs as Gadafi has been called upon famously by President Reagan, but whatever onemay call these guys they are and will continue to be brainy people.
On a latter note I should also say this, whatever Gadafi had, whatever evil work he has taken part in each and every one of these people contributed to the development of their countries, I say this because neither Tunisia, Egypt nor Libya are poor countries. They are all nations who were trying to live up to their potential. So killing Gadafi in the middle of the day after he was captured, does not put an end to anything, it just add oil to a flame that is and continue burn in the future, because some individuals just can't resist trying to leave an everlasting memory in human history, they just want it all, its just human nature.
