The Islamic State is still able to inspire terror attacks around the world, even though U.S. strikes have made it harder for the terrorist group to direct those attacks, National Counterterrorism Center Director Nicholas Rasmussen told a Senate committee on Wednesday.

“One thing that I think that I pointed to this year that was not on the table last year is we have seen a reduction in the ability of ISIS to be able to actually direct and command and control attacks from their safe haven in Iraq and Syria,” Rasmussen said at a Senate Homeland Security and Governmental Affairs Committee hearing.
