This chapter examines Arab nationalism after the Six Day War of June 1967, which was a seminal event in Arab contemporary history. What the Six Day War did was to irretrievably rob Arab nationalism of the crucial element of unification. While Arabs—in whatever state they lived—continued to recognize their membership in the cultural space called “the Arab world,” a recognition shared by rulers and subjects alike, they no longer truly believed in the viability of organic political unity. The Six Day War had also cost Egypt dearly in life and material. Moreover, beyond these horrendous losses, the war was responsible for many domestic and economic maladies.
