Thus far, recent protests in the Arab world have led to different political outcomes including regime change, civil war, and suppression by regime. The present paper explores the reasons behind these different outcomes. The research methodology is a comparative case study approach, and five countries of Tunisia, Egypt, Bahrain, Libya, and Syria are examined. The hypothesis is that the different political outcomes of the protests are due to a combination of factors, including the level of mobilization of anti-regime movements, the responses of national militaries, and finally the reaction of international powers. Different configurations of these components in the crisis-stricken countries have led to different political outcomes.
