Ex-US Intelligence Chief on Islamic State's Rise: 'We Were Too Dumb'

There were all kinds of strategic and tactical warnings and lots of reporting. And even the guys in the Islamic State said that they were going to attack overseas. I just don't think people took them seriously. When I first heard about the recent attacks in Paris, I was like, "Oh, my God, these guys are at it again, and we're not paying attention." The change that I think we need to be more aware of is that, in Europe, there is a leadership structure. And there's likely a leader or a leadership structure in each country in Europe. The same is probably similar for the United States, but just not obvious yet.
