Via The Blaze, former deputy director of the CIA Mike Morrell talked to CBS News about the threat that the Islamic State poses to the United States:

After explaining what he thought needed to be done to defeat the terrorists (more targeted strikes and better intelligence), he said that “if an ISIS member showed up in a mall in the United States tomorrow with an AK-47 and killed a number of Americans I would not be surprised.”

“Over the long-term, I worry that this group could present a 9/11-style threat,” he added, noting the group presents both a short-term and long-term threat.
