The Saudi-Iranian Rivalry and the Future of Middle East Security (Enlarged Edition)

The Middle East is undergoing an era of revolutionary change that is challenging the foreign policies of the United States and virtually all regional states. In this new environment, opportunities and challenges exist for a number of regional and extra-regional states to advance their national interests, while attempting to marginalize those of their rivals. Despite these changes, the Arab Spring and revolutions in countries such as Tunisia, Egypt, and Libya have not altered some of the more fundamental aspects of the Middle East regional situation. One of the most important rivalries defining the strategic landscape of the Middle East is between Iran and Saudi Arabia. The competition between these two states is long-standing, but it is especially important now. Political relationships that have endured for decades, such as the one between Iran and Syria, now seem to be in some danger, depending upon how current struggles play out.
