The youth revolution in Yemen at the beginning of 2011 kindled a ray of hope that the walls of tyranny could be broken down and the country could be pulled back from the clutches of narrowly defined identities. It sharpened the will that formed a “historical bloc” capable of rendering democratic transition successful. However, the youth revolution never transcended the ecstasy of a romantic revolutionary act to reach the stage of building institutions capable of enforcing respect for the law and accommodating ethnic, tribal, sectarian and political pluralism. This study addresses the impact of the Saudi-Iranian role on Yemen's transition. It is premised on considerable importance attached regional factors, which perhaps have even greater influence than domestic factors on the outcome of the Yemeni revolution. The study stresses that the effects and limits of regional factors are related to several variables, such as the vicissitudes of international politics; international and regional balances and interests; as well as the strategic location of the country subject to interference; its resources; its internal dynamics; the maturity of local elites; the weight of political opposition; and the quality of institutions.
