We're doing a lot and we're doing it in various fora.
We participate in a more globalized coalition of countries called the global coalition against terrorism, and inside that global coalition there is a working group dedicated to terrorist financing.
We also participate in something called the anti-ISIL coalition, another coalition of countries. One of its lines of effort has to do with terrorist financing. There we also work with allies in sharing information and sharing best practices in determining how best to cut back these flows.
The best example I can give you has to do with the question of where ISIL gets its money and how we can cut it off. We're working with our partners, for example, to deny them access to the international financial institutions, and I think we've had a good deal of success in that regard, but our adversary finds different ways to move money and is not always using international banks. That's a bigger challenge for us, but we're working, with our allies in the region in particular, on that challenge.
One of the other major ways in which ISIL raises money for itself is through the smuggling of oil and through illegal taxation of residents of the area. That's much more difficult, because it is happening on the ground. I should say that the coalition is taking direct action against these illegal oil wells and is actually bombing some of those facilities and taking action against oil tankers that are syphoning the oil out, and I think we're having some impact there.
We're also taking action at the global level under things such as the Financial Action Task Force, whereby we're looking at the use of international financial institutions. We're working at the regional and local level, taking direct action against terrorist groups like ISIL.
