Two weekends ago in Orlando, Fla., in the wee hours of the morning, a gunman opened fire in a gay nightclub teeming with revelers. After killing and wounding scores of people, he took hostages in a restroom. He began calling police and media outlets, began crafting social-media posts, all for the point of announcing what was already clear to the nightclub denizens who’d heard him screaming, “Allahu Akbar!” — Allah is greater! — as he fired shot after shot: Omar Mateen was a stealth Muslim militant.
He was an adherent of radical Islam who committed his atrocity in furtherance of its ongoing jihad against America and the West. He took time in the midst of the carnage to make bayat — a pledge of allegiance — to Abu Bakr al-Baghdadi, the emir of the Islamic State terror network and its proclaimed caliphate.
