Political ideas make their own realities. Often in defiance of logic, they hold men and are in turn held by them, creating a world in their own image, only to play themselves out in the end shackled by routine problems not foreseen by those who spun the myth, or living past their prime and ceasing to move people sufficiently. Or, political ideas turn to ashes and leave behind them a trail of errors, suffering and devastation.
An idea that has dominated the political consciousness of modern Arabs is nearing its end, if it is not already a thing of the past. It is the myth of pan-Arabism, of the Umma Arabiyya Wahida Dhat Risala Khalida, "the one Arab nation with an immortal mission." At the height of its power, pan-Arabism could make regimes look small and petty: disembodied structures headed by selfish rulers who resisted the sweeping mission of Arabism and were sustained by outside powers that supposedly feared the one idea that could resurrect the classical golden age of the Arabs. As historian Bernard Lewis summed it up little more than a decade ago, allegiance to the state was "tacit, even surreptitious," while Arab unity was "the sole publicly acceptable objective of statesmen and ideologues alike."  What this meant was that states were without sufficient legitimacy. Those among them that resisted the claims of pan-Arabism were at a disadvantage- their populations a fair target for pan-Arabist appeals, their leaders to be overthrown and replaced by others more committed to the transcendent goal. Now, however, raison d'etat, once an alien and illegitimate doctrine, is gaining ground. Slowly and grimly, with a great deal of anguish and of outright violence, a "normal" state system is becoming a fact of life.
No great idea passes from the scene without screams of anguish, protests of true believers, and assertions by serious analysts that the idea still stands - battered, transformed but standing nonetheless - and debate about the vitality of pan-Arabism continues, for it
