The League of Arab States (also known as the Arab League) is well past its sixth decade of establishment. However, it has a long way to go to achieve the objectives enumerated in its charter. In a sense, there is much stronger propensity towards disintegration than integration in the League. This article seeks to study the reasons that account for the failure of such integration in the Arab League. Current trends in the Arab Union are studied through the lens of Neorealist Theory. To that end, the paper seeks to find an answer to this question: What are the reasons for the failure of integration in the Arab League? The main hypothesis of this article is that the member states’ main concern is survival, security, and relative gains rather than convergent cooperative behaviors conducive to integration; as a result, six decades after its birth, integration is yet to be achieved.
