There are a number of issues inhibiting the coordination of a comprehensive plan to economically reconstruct and rehabilitate war-torn Arab states, including internal political discord within Arab states and the Gulf Cooperation Council (GCC); discord between state actors in the region, particularly between the Gulf states, Iran and Turkey; and the roles of new international actors. Considering the historical example of the Marshall Plan, this project considers the possible contours of a multilateral effort by the European Union, the UK, the US and the GCC to reconstruct and stabilize the countries of the Arabian Peninsula, particularly Syria, Iraq and Yemen in a way that is both economically sustainable and conducive to the region’s long-term stability.
