I want to thank the witnesses for their presentations. They've been very, very informative.
I'm especially interested in the general concept that we're looking at a generational problem, so there's no quick and easy solution. We really do need to be looking at the long term here.
If I could bring it back to some immediate concrete measures that we might be able to take, one of the measures that was discussed was financial. You mentioned that ISIL may have betrayed a certain financial requirement through recent ransom demands for $200 million. I'm interested in seeing what we have done to try to stem financial flows to ISIL. There was mention at one point that they were robbing banks. I'm assuming they're robbing banks within their own territory and not outside the territory. What are we doing to stop financial flows into that territory? Is there anything more we can do?
