Today Charles Krauthammer focuses on the failure of Barack Obama’s “Cairo Doctrine.” This was the policy of servile obedience to radical islamists that Obama served up as an alternative to the Bush years. Apparently being merely safe wasn’t enough for Obama.

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.

Read it all. You won’t regret it.
