Analysts say Turkey is keeping Daesh in business through oil sales, but more broadly, facilitating the rise of the terrorist group for years by providing supply routes across its border with Syria.
The suggestion is that Turkey also supports – directly or indirectly – other extremist and terrorist groups in Syria such as Jabhat al-Nusra (al-Nusra Front), which is the official al-Qaeda franchise in the country. And without Turkish support, as well as Western, Saudi and Qatari support, terrorist groups like ISIL and Nusra would probably be severely weakened and would eventually die out.
Syria’s most potent oilfields are in Deir Ezzor Province, which is largely under ISIL control. The Takfiri terrorist group is said to earn most of its money by taxing locals and confiscating valuables at checkpoints, but oil sales still account for hundreds of millions of dollars of revenue. Daesh uses this money to expand and manage vast areas under its control, which is home to about five million people.
