U.S. Intensifies Effort to Blunt ISIS’ Message

WASHINGTON — The Obama administration is revamping its effort to counter the Islamic State’s propaganda machine, acknowledging that the terrorist group has been far more effective in attracting new recruits, financing and global notoriety than the United States and its allies have been in thwarting it.

At the heart of the plan is expanding a tiny State Department agency, the Center for Strategic Counterterrorism Communications, to harness all the existing attempts at countermessaging by much larger federal departments, including the Pentagon, Homeland Security and intelligence agencies.

The center would also coordinate and amplify similar messaging by foreign allies and nongovernment agencies, as well as by prominent Muslim academics, community leaders and religious scholars who oppose the Islamic State, also called ISIS or ISIL, and who may have more credibility with ISIS’ target audience of young men and women than the American government.

With the Islamic State and its supporters producing as many as 90,000 tweets and other social media responses every day, American officials acknowledge they have a tough job ahead to blunt the group’s digital momentum in the same way a United States-led air campaign has slowed ISIS’ advances on the battlefield in Iraq and, to a lesser extent, in Syria.

“Unfortunately, as we all know, the government is probably not the best platform to try to communicate with the set of actors who are potentially vulnerable to this kind of propaganda and this kind of recruitment,” Nicholas Rasmussen, the director of the National Counterterrorism Center, told the Senate Intelligence Committee last week.

“We try to find ways to stimulate this kind of counternarrative, this kind of countermessaging, without having a U.S. government hand in it,” Mr. Rasmussen continued. “People who are attracted to this don’t go to the government for their guidance on what to do, not the U.S. government and certainly not their governments in the Middle East.”
