Arab nationalist ideologies failed across economics, unity, and crisis. [causal]
Both Nasserism and Ba'athism failed to achieve Arab unity and to resolve the problem of Israel and the Palestinians. Nowhere was economic performance brilliant, and Nasser's Egypt in particular sank into destitution and cultural decline. The new classes in power were often painfully reminiscent of the old. The June 1967 fiasco raised the question of the adequacy of old ideas for solving the pressing problems of the day. Every major problem, every failure, every crisis that arose . . . led to feelings that something was lacking in nationalist ideology, that other important ideologies should be looked to as sources of fresh ideas.
