The New York Times mentions Atlantic Council event featuring Undersecretary of Defense for Intelligence Michael Vickers:
“In some respects, they look like ISIL two years ago,” Michael G. Vickers, the undersecretary of defense for intelligence, told the Atlantic Council last week, using another name for the militant group known as the Islamic State. “How fast their trajectory can go up is something we’re paying a lot of attention to. But certainly in their area, they’re wreaking a lot of destruction.”
