ISIS Pushing US into 'New Environment' in Threats Against Homeland, Homeland Security Secretary Says

Role of Internet in extremism makes attacks harder to predict, said Jeh Johnson.

The Pentagon raised the alert level at domestic military bases last week in response to calls for attacks on military installations from ISIS and other groups. It is the first time the threat level has been increased since the 10th anniversary of the 9/11 attacks and will result in increased security measures on all U.S. bases.

“It has to come from within the community,” he said. "It has to come from Islamic leaders, who frankly can talk the language better than the federal government can and so when I meet with community leaders, Islamic leaders, that’s one of the things that we urge them to do."

NYPD Deputy Director of Intelligence and Counterterrorism John Miller echoed the secretary’s message that the community should be more involved in countering extremist messages.

“This can’t be a government effort, if a government effort that’s countering a call for violence that’s clothed in religion is coming from the government it’s already poisoned,” Miller said on “This Week.” “This needs to come from those credible voices in the community.”

Miller said he and Johnson met with Muslim community leaders in New York last week. Some members of those communities said the federal government has not done enough to stop surveillance and investigations that target Muslims. Miller said he understood their concerns but still hopes community leaders will be more engaged in the counter-message.
