Don’t call it a comeback. Al Qaeda, the group responsible for the worst terrorist attack in United States history, never really left. Instead, while news media coverage inordinately focused on the Islamic State, al Qaeda re-tooled and re-established itself for a new age.

To paraphrase Mark Twain, reports of al Qaida’s death were greatly exaggerated. Anticipatory obituaries appeared after the death of al Qaida founder Osama bin Laden on May 2, 2011. Then-President Barack Obama, for instance, said on Sept. 10, 2011 that al Qaeda was “on a path to defeat.” Similarly, then-Secretary of Defense Leon Panetta said in July 2011 that the U.S. was “within reach of strategically defeating al Qaeda.”
