The Arab revolutions have changed the political and security landscape of the Persian Gulf. The upheavals have altered the sources of threats states used to feel from those emanating from outside the internal ones; the unrest in Bahrain and Saudi Arabia has proved that the sources of tension for the Arab states are quite societal. As a result, the old Arab tactic of attribution of domestic challenges to alleged Iranian interventionism is now obsolete. The traditional role played by the regional powers is also affected and the regional alignments are in flux. The overthrow of the Mubarak regime along with the U.S middle of the way approach during the Arab revolutions have elevated Iran’s stance in the Persian Gulf at the expense of the U.S and the GCC. Moreover, the security interdependence of the Persian Gulf states, particularly among the GCC, is tightened and in the face of increasing security challenges, the monarchical bloc is revitalized with the aim to buttress Arab regimes. All the said developments are the subject of examination in this article through application of the regional security complex (RSC) theory.
