I have a question for Mr. Gartenstein-Ross. I found your comments around propaganda use and messaging to be very interesting. Actually, a couple of witnesses touched on this subject.
Based on your assessment, what is an effective way of disrupting this? Obviously, as a responsible actor, we have a responsibility to do what we can here under the United Nations Security Council resolution, but also in the region. Do you have ideas around that?
I was very interested in your assessment that while the public seems to think that Daesh or ISIL is gaining momentum and is on a roll, you're suggesting that they're very vulnerable. I appreciate your assessment, but what are some of the things we can do to effectively disrupt and hamper their actions, particularly in, as you quite rightly put it, their messaging, the way they use propaganda?
