“You’re not going to be the leader in the global jihad without striking America,” FBI Director James B. Comey told the House Homeland Security Committee.
Matthew G. Olsen, director of the National Counterterrorism Center, said there’s already some evidence of the feud. He said a recent announcement by al Qaeda that they’ve added a new affiliate in Asia “could be viewed as an effort by core al Qaeda to reassert its supremacy in this global environment.”
Islamic State militants have been on the ascendance in Syria and Iraq, fielding an army estimated at more than 30,000 fighters and occupying territory in both countries. Its successes have drawn in new recruits and money.
The intelligence and security officials also said the Islamic State has a sophisticated public relations operation that has helped it gain attention — including several high-profile beheadings of journalists, which the Islamic State revealed in Internet videos.
