ISIS has become quite a self-financing terrorist network with their theft of oil, selling it on the black market with their destruction and seizure of antiquities, selling that on the black market, with their taking over Mosul and raiding the banks. They've got a source of funding, so I don't really know. But I know that the - that Saudi individuals have certainly funded other related terrorist groups over time and also exported a lot of Wahhabi radicalism by kicking out or sending out imams and teachers to set up schools and mosques to preach that particularly harsh brand of Islam. So the Saudis have a lot that they can do to both stop and then to help.
