Arab Unity and Disunity emphasizes the significance of the historical perspective in arriving at accurate generalizations concerning the present social, economic, and political factors affecting the movement toward unity of the Arab states. Topics discussed in the book include Arab unity and disunity before, during and after Mohammed's time, the prime movers behind the Arab national movement after World War I, and the West's betrayal of the Arab cause. The book also analyzes the reasons for the inability of the Arabs to replace their local and narrow asabiyahs (solidarity, unity) with the wider, more comprehensive, Arab unity.
