Thanks. I think it's a useful clarification.
One comment I will make is that these, I don't want to call them taxes now, but this extortion has been a very important source of revenue for Daesh, especially recently, because the coalition has bombed several of the oil fields they were using to have access to resources. So they've been relying a lot on those taxes. With the territorial loss they're suffering now, their resources are seriously curtailed.
