Chechen and Triad Mobs have been doing it for years. The Russian mafia has been doing it for their support of Syria which use to be a safe heaven for Russian crime Lords till Putin got involved. There is money to be made with ISIS, and they have the money to spend due to now they pretty much have an terrorist state. If there is money to be made, then there will always be guys looking for a cash flow. Don't be surprise, it is only business for these people, patriotic comes later for them, they look at the dollar signs first.
