Contributor(s): F. Gregory Gause, III | The contest for influence in the post-Arab Spring Middle East is being played out in the domestic politics of states where governance is weak, collapsing or collapsed. Saudi Arabia, Iran, Turkey, Israel and other states seek to gain influence and check each other by finding allies in the domestic political struggles of Syria, Iraq, Lebanon, Palestine, Yemen and elsewhere. Meanwhile, ideological struggles in both Sunni and Shia Islam and between more Islamist and more secular forces complicate the already difficult task of reconstructing state authority, inviting foreign intervention and influence across the region.

From 1997 to 2008 he was director of the university's Middle East Studies Program and from 2010 to 2013 he was chair of the Political Science Department.
