You haven’t heard of the Khorosan Group because there isn’t one. It is a name the administration came up with, calculating that Khorosan — the –Iranian–​Afghan border region — had sufficient connection to jihadist lore that no one would call the president on it.

The “Khorosan Group” is al-Qaeda. It is simply a faction within the global terror network’s Syrian franchise, “Jabhat al-Nusra.” Its leader, Mushin al-Fadhli (believed to have been killed in this week’s U.S.-led air strikes), was an intimate of Ayman al-Zawahiri, the emir of al-Qaeda who dispatched him to the jihad in Syria. Except that if you listen to administration officials long enough, you come away thinking that Zawahiri is not really al-Qaeda, either. Instead, he’s something the administration is at pains to call “core al-Qaeda.”…

The president has been telling us for years that he handled al-Qaeda by killing bin Laden. He has been telling us for weeks that the Islamic State — an al-Qaeda renegade that will soon reconcile with the mother ship for the greater good of unity in the anti-American jihad — is a regional nuisance that posed no threat to the United States. In recent days, however, reality intruded on this fiction. Suddenly, tens of thousands of terrorists, armed to the teeth, were demolishing American-trained armies, beheading American journalists, and threatening American targets.
