It is absolutely clear that the Daesh's oil is being shipped through Turkey: it can't be being shipped west through territory controlled by the Syrian government, it can't be shipped east or southeast through Shi'ite or Kurdish controlled lands, leaving only Turkey or Jordan. Jordan is a non-starter (pro-Western, a monarch who has a better claim to be a successor to Mohammed than the upstart Daesh "Caliph", good security services, very little port capacity, and to top that off, the Daesh earned the undying emnity of Jordanians by burning their pilot alive), leaving Turkey. However, Turkey is not buying the Daesh's oil, just serving as a conduit and profiting from the trade.
I would agree....it’s nickels and dimes on Turkey’s back...they just take the pay-offs and allow a conduit to exist. But these are all relatives or friends of Erdogan who profit off this.
