I guess it’s official now: The term “Arab Spring” has to be retired. There is nothing springlike going on.

The broader, but still vaguely hopeful, “Arab Awakening” also no longer seems valid, given all that has been awakened. And so the strategist Anthony Cordesman is probably right when he argues: It’s best we now speak of the “Arab Decade” or the “Arab Quarter Century” — a long period of intrastate and intraregional instability, in which a struggle for both the future of Islam and the future of the individual Arab nations blend together into a “clash within a civilization.” The ending: TBD.
