Thank you very much for your testimony. Please don't think me rude if I interrupt you. I only have seven minutes today, and I want to ask three questions. My first is for Dr. Akhavan.
Many people have mentioned the lifeblood to ISIS of funding—I'm not talking about black-market oil—from countries like Saudi Arabia, Qatar, Turkey, and others. Is it realistic to be able to stop that flow? Do you know if the governments of those countries are doing anything to try to stop that flow? It's certainly an important element.
