It’s now three years since the Cairo speech. Look around. The Islamic world is convulsed with an explosion of anti-Americanism. From Tunisia to Lebanon, American schools, businesses and diplomatic facilities set ablaze. A U.S. ambassador and three others murdered in Benghazi. The black flag of Salafism, of which al-Qaeda is a prominent element, raised over our embassies in Tunisia, Egypt, Yemen and Sudan.

The administration, staggered and confused, blames it all on a 14-minute trailer for a film no one has seen and may not even exist. …

It’s as axiomatic in statecraft as in physics: Nature abhors a vacuum. Islamists rush in to fill the space and declare their ascendancy. America’s friends are bereft, confused, paralyzed.

Islamists rise across North Africa from Mali to Egypt. Iran repeatedly defies U.S. demands on nuclear enrichment, then, as a measure of its contempt for what America thinks, openly admits that its Revolutionary Guards are deployed in Syria. Russia, after arming Assad, warns America to stay out, while the secretary of state delivers vapid lectures about Assad “meeting” his international “obligations.” The Gulf states beg America to act on Iran; Obama strains mightily to restrain . . . Israel.
