Uprising Arab

Uprising in the Arab countries these days is increasing day by day! Why are the people of various Arab countries especially Tunisia, Bahrain, Syria, Egypt, Algeria and Libya going against their governments to overpower? What are the causes that stirred up the people to get rid of their rulers? Do America and its allies have their vested interests in Arab world? How long will the uprising remain underway and what countries in future will be the victim of it?! Basically uprising broke out from Tunisia. Gradually revolt engulfed various Arab countries including especially Egypt, Libya, Bahrain, Syria etc. The insurgency in Algeria, Bahrain, Yemen, Jordon and Morocco ended time by time but the circumstances in Tunisia, Egypt, Libya and Syria worsened a lot! As a result, Tunisia, Egypt and now Libya have been overpowered by the rebels whereas Syria is still in trouble! On the other hand, Saudia Arabia took some good initiatives in favor of its nation to escape from any uprising and really it succeeded!
